Allosteric signalling in the outer membrane translocation domain of PapC usher

PapC ushers are outer-membrane proteins enabling assembly and secretion of P pili proteins in uropathogenic E. coli, allowing them to infect the human urinary tract and cause disease. To pass through the outer membrane of the E. coli cell, a P pili protein must travel through the translocation domain of PapC. The translocation domain is a large β-barrel occluded by a middle domain (plug domain), which is only marginally stable, to allow the opening of the barrel. Previous studies suggested that this gating mechanism is controlled by two elements of the translocation domain – a β-hairpin and an α-helix, but it is not clear how.

To investigate the role of these elements in allosteric signal communication, we developed a hybrid computational method combining evolutionary and molecular dynamics studies. Our starting point was molecular dynamics simulations on 4 different models: the native protein structure, two mutants in which the helix or β-hairpin is deleted, and a mutant in which both are deleted. Polar interactions observed during the simulations were compared in all systems in order to detect interactions that change upon mutation. Additionally, we used evolutionary analysis, relying on both amino acid conservation and coupling (co-evolution) to highlight particularly important interactions. The data were combined in a large hybrid residue interaction network. Using graph theory approaches, we showed that certain regions of the β-barrel, located mostly on one side of the barrel, are likely involved in moving the plug domain. This unique computational approach allowed us to detect key amino acids in these distinct regions (residue ‘communities’) that likely control the position of the plug in the pore, thereby regulating PapC gating and usher’s activation.

The predictions were tested by experiments, in collaboration with the Waksman group and two groups in the US – Delcour group at the University of Houston and Thanassi Group at Stony Brook University. Antibiotic sensitivity and electrophysiology experiments on a set of alanine-substitution mutants confirmed functional roles for four communities. Our results suggest that residues around β12–β14 that are beneath the α-helix act as a regulator of β 12- β 13 loop (the ‘latch’) that controls the opening and closing of the β-barrel. Taken together, the study illuminates the gating mechanism of PapC ushers and its importance in maintaining outer-membrane permeability.

Taking Steps Towards Elucidation of Kinesin Motor Mechanochemistry

In the crowded environment of a eukaryotic cell, long-distance active transport by molecular motors is essential. Cellular dysfunction and disease - including paralysis and neuropathy - ensues when these transport processes break down.

Kinesins are a superfamily of motors that move along microtubule tracks within the cytoplasm, powered by energy from ATP binding and hydrolysis. Kinesins are defined by their conserved motor domains, which contain both ATP- and microtubule-binding sites. The rest of the kinesin molecule extends away from the microtubule. Dimerization is mediated by coiled-coil formation between two protomers. At the distal end of the dimeric molecule, cargo – such as vesicles and mitochondria - are attached to allow transport to their appropriate cellular destination. The two kinesin chains within the dimer work together to take directional steps along the microtubule, powered by ATP.

To take these steps, each kinesin motor domain in the pair must undergo alternating cycles of tight association and release from their tracks. This cycle is coordinated by binding and breakdown of ATP, which also provides the energy needed to take the next step. How the cycle of loose and tight microtubule attachment is coordinated with release of the breakdown products of ATP, and how the energy from the ATP molecule is converted into the force that moves the motor along the microtubule, has been unclear.

Answering structural questions about motor mechanism is challenging because high spatial resolution is needed to study conformations that usually only last fractions of a second. In addition, the complexes formed by kinesins and their microtubule tracks are large and dynamic. We solved these challenges by determining a sequence of structures using cryo-electron microscopy and image reconstruction. We thereby obtained multiple snapshots– in more detail than previously seen (at ~7Å resolution) – of the motor domains of two types of kinesin, called kinesin-1 and kinesin-3. In collaboration with Maya Topf’s group, we also calculated pseudo-atomic models of these motors.

Our structures show the way in which interaction with the microtubule causes shape changes in the motor domains to stimulate release of the breakdown products of ATP from the previous cycle. This release makes room for binding by a new ATP molecule. When ATP binds, it in turn causes structural changes that allow the next step to be taken. This mechanism involves tight coupling between track binding and fuel usage and makes kinesins highly efficient motors. Previously, kinesin-1 and kinesin-3 were thought to move along the microtubule tracks in different ways; however, our structures show that the core mechanism used by their motor domains is, in fact, the same. Our new structures also provide unprecedented insight into how the stepping mechanism can be disrupted by disease-causing mutations in the kinesins. Future work will clarify whether the key features observed in the motor domains of kinesin-1 and kinesin-3 are also found in other types of kinesin motors. This work was funded by the MRC. Joe Atherton will present this work at a Friday Wrap (24/10/14).

Cipla Distinguished Fellowship for Dr Sanjib Bhakta
August 2014

Dr Sanjib Bhakta, Reader in Molecular Microbiology and Director of Mycobacteria Research Laboratory (MRL) in the Department of Biological Sciences and the Institute of Structural and Molecular Biology, has been awarded a prestigious Cipla Distinguished Fellowship in Pharmaceutical Sciences for his outstanding research on tackling antibiotic resistance in tuberculosis.

On his trip to India in July, Dr Bhakta gave the Cipla endowment lecture entitled Tackling antibiotic resistance in TB at the University Institute of Chemical Technology (ICT), Mumbai (India). In his lecture, Dr Bhakta spoke about inter-disciplinary approaches in novel therapeutic intervention to tackle drug resistance in M. tuberculosis and discussed techniques developed exclusively in his laboratory to evaluate potential anti-infective molecules. Highlighting some of the current work being carried out in his laboratory Dr Bhakta spoke about understanding ligand-protein interaction to unveil the mechanisms of action of anti-mycobacterial compounds. Dr Bhakta’s lecture will be published in the annual journal of ICT, the Bombay Technologist.

During his visit to ICT, Mumbai, Dr Bhakta also met the departmental heads, academic course coordinators and deans and offered a career acceleration mentoring session for graduate researchers and post-doctoral students. Collaboration between ICT and Birkbeck's Mycobacteria Research Laboratory is not new and existing relations will be consolidated and developed in the future, once a draft material transfer agreement and memorandum of understanding is implemented. In addition, a group of distinguished professors from ICT will visit Birkbeck later this year. Collective work between these two universities will benefit from the availability of potential anti-tubercular agents of natural, semi-synthetic and/or synthetic origin and the technical expertise of Dr Bhakta in evaluating the effectiveness of these novel agents towards new anti-infective drug development.

While in India, Dr Bhakta also visited a number of other universities, colleges, research institutes and non-governmental organizations to shed light on the world-class research being carried out by MRL researchers in the field of tuberculosis drug design and to discuss new health and diseases research and educational initiatives between UK and India. Dr Bhakta has been working with the Indian Development Foundation (IDF) since 2009 and this year he was elected as IDF’s honorary international consultant for TB research. Established in 2005, the IDF is a non-government organisation with goals to improve education, development and health in rural parts of India. Its activities have been key in the elimination of leprosy in India, and it is now focused on combatting tuberculosis and other diseases.

ISMB Symposium 2014
June 2014

The sixth biennial ISMB research symposium was held in mid-June 2014 in Birkbeck’s Clore Management Centre. Its packed two-day scientific programme followed the pattern of previous symposia, featuring fifteen excellent lectures from both distinguished researchers and rising newcomers.

The programme was divided into sections covering all the Institute’s research areas, with a sixth discipline, proteomics and mass spectrometry, added to those covered in 2012: structural biology, computational biology, biophysics, chemical biology and biochemistry with cell biology. One speaker in each section was a core member of the ISMB. The symposium was supported by both Birkbeck and UCL at the highest level; it was opened by Geraint Rees who is shortly to take on the role of Dean of the Faculty of Life Sciences at UCL, and closed by Nicholas Keep, who holds an equivalent position at Birkbeck. Both deans paid tribute in their remarks to the vision, energy and leadership of the Institute’s director, Gabriel Waksman.

For the first time in its 12-year history, the ISMB had the honour of welcoming a Nobel laureate as a symposium speaker. This was Venki Ramakrishnan, whose share of the 2009 Nobel Prize for Chemistry was awarded for structural studies of the ribosome. He described his most recent structure, the first high-resolution structure of the large subunit of a mitochondrial ribosome. The tunnel through which a growing protein chain emerges from this ribosome takes a different path, possibly to position the protein close to the mitochondrial membrane.

The other external speaker on structural biology, Werner Kühlbrandt from Frankfurt, Germany, described the structure of a human ion transport protein and showed how the organisation of the mitochondrial membrane is disrupted during ageing. In an inspiring talk, Shankar Balasubramanian from the University of Cambridge described how his research into DNA synthesis led to the development of a solid-state technique for DNA sequencing that is many orders of magnitude faster than those used in the 15-year long Human Genome Project. Thanks in part to this technology it is now possible to sequence a dozen or so human genomes in a few days. Despite this success, Balasubramanian still works in basic research, using DNA sequencing with simple chemistry to distinguish between different modifications of the base cytosine.

A number of other speakers also described research into nucleic acids and their interactions with proteins. Achilles Kapanidis from the University of Oxford described using a fluorescence-based technique, single-molecule Főrster resonance energy transfer (FRET) as a “molecular ruler” to investigate structures formed during the process of DNA transcription that are too transient to be observed using more traditional methods. Albert Heck from Utrecht University in the Netherlands described a protein-RNA complex termed Cascade, which helps to defend bacteria against attack by viruses. His group used mass spectrometry to determine this unusual, spiral structure. And, speaking in the chemical biology section, Christopher Hunter from the University of Sheffield explained how his group used computational techniques to predict the way that DNA winds round proteins to pack into the cell nucleus.

In the cell biology programme, Marino Zerial from Dresden, Germany, presented a new model for liver tissue structure with an ordered network of capillaries and bile channels, and UCL’s Alison Lloyd explained the mechanism through which nerve cells regenerate following injury. Soren Brunak from the Technical University of Denmark presented an unexpected aspect of computational biology in discussing his automatic analysis of medical records. This has uncovered some unexpected genetic linkages, for example, finding one gene – THRA - that links male pattern baldness with migraine.

The next ISMB symposium will take place in June 2016.

Research by Dr Kate Bowers into Developing Novel, In Vivo Assays for Eukaryotic Membrane Fusion
May 2014

Dr Kate Bowers of the ISMB is among a group of scientists who have developed novel assays for eukaryotic membrane fusion in vivo. Membrane fusion in eukaryotic cells is an essential cellular process involved in (for example) organelle biogenesis, protein trafficking, fertilization, muscle biogenesis and pathogen invasion. In vitro studies in yeast, using purified vacuoles, have been instrumental in determining the cellular machinery required for membrane fusion. These studies have implicated the vacuolar H+-ATPase (V-ATPase) as part of the fusion machinery. The V-ATPase is a multisubunit, rotary proton pump, and models formulated from in vitro yeast studies suggest that it is the proteolipid proton-translocating pore of the V-ATPase that functions in fusion, with further studies in worms, flies, zebrafish, and mice supporting this model.

Some years ago, Kate Bowers and Nia Bryant (University of Glasgow*) set up a new assay to measure membrane fusion in vivo. Using this assay, they were able to show that the proteolipid proton-translocating pore of the V-ATPase is not part of the fusion machinery. Complementary experiments, using another in vivo assay developed by Tom Stevens and his group (University of Oregon) supported this conclusion. The team from UCL, Glasgow and Oregon were then able to show conclusively that while acidification is required for the fusion of yeast vacuoles, the physical presence of the V-ATPase is not. This work is important as it will lead to a re-evaulation of models of membrane fusion in yeast and higher organisms, and ultimately to the greater understanding of this essential cellular process.

Professor Christine Orengo elected member of EMBO
May 2014

Congratulations to Professor Christine Orengo who has been elected as a new member of EMBO in recognition of outstanding research in the life sciences. Professor Orengo (UCL Division of Biosciences) was one of 106 “outstanding researchers in the life sciences” that were elected to be European Molecular Biology Organisation (EMBO) members in 2014.

Christine Orengo’s research has focused on how proteins evolve – how do relatives in a family diverge in structure and function and how do they evolve to operate in different biological contexts. Nearly 20 years ago she established the CATH classification of protein domains, together with Janet Thornton, which is widely accessed (nearly 2 million webpage accesses and 10,000 unique visitors per month) and a partner resource in InterPro.

CATH was enabled by the development of robust protein structure comparison algorithms, (SSAP - JMB 1989, CATHEDRAL – PloS Comp Biol 2007) still used by the structural biology and structural genomics communities. Her group participate in two large structural genomics initiatives which exploit CATH for targeting pathogenic proteins (JMB 2005, Structure 2009). Analysis of CATH led to important insights into the population of structural families and folds (Nature 1994) and revealed the bias in protein domain families whereby less than 5% account for two thirds of all known domains (Annual Reviews Biochem. 2005, NAR 2006).

CATH analyses also revealed expansions of functional repertoires in bacteria (TIG 2005), novel structural motifs (Structure 1993) and structural mechanisms mediating changes in protein functions (JMB 2006, TIBS 2009, Structure 2010). More recently, with the assignment of 20 million domains to CATH, sequence analysis has enabled the recognition of functional subfamilies possessing distinct sequence patterns that can aid function prediction (NAR 2010, Nature Methods 2012). The group also study evolution of functions in CATH superfamilies (TIBS 2002, PNAS 2013). CATH domain families have also been exploited in the prediction and analysis of protein networks (PLoS Comp Biol 2009, Pain 2013) and the group collaborate with several experimental groups characterising signalling networks implicated in development, neuropathic pain and cancer.

Research by the Waksman Lab into Bacterial Secretion Sheds Light on Antibiotic Resistance
March 2014

A team of scientists led by Professor Gabriel Waksman has uncovered the system that allows the sharing of genetic material between bacteria, and therefore the spread of antibiotic resistance. The research, published in Nature and funded by the Wellcome Trust, reveal the mechanism of bacterial type IV secretion, which bacteria use to move substances across their cell wall.

As type IV secretion can distribute genetic material between bacteria, notably antibiotic resistance genes, the mechanism is directly responsible for the spread of antibiotic resistance in hospital settings. It also plays a crucial role in secreting toxins in infections - causing ulcers, whooping cough, or severe forms of pneumonia such as Legionnaires’ disease. Using electron microscopy the team were able to reconstruct the system as observed in the bacteria E. coli. They saw that the mechanism consists of two separate complexes, one in the outer membrane of the cell, and the other in the inner membrane, which are connected by a stalk-like structure that crosses the periplasm – the space between the two membranes. The complexes at both the inner and outer membranes form pores in the membrane, via which substances can be secreted.

Professor Waksman said: ‘This work is a veritable tour de force. The entire complex is absolutely huge and its structure is unprecedented. It is the type of work which is ground-breaking and will provide an entirely new direction to the field. Next, we need to understand how bacteria use this structure to get a movie of how antibiotics resistance genes are moved around.’ ‘Understanding bacteria’s secretion system could help design new compounds able to stop the secretion process, thereby stopping the spread of antibiotics resistance genes. Given that antibiotics resistance has become so widespread and represents a grave threat to human health, the work could have a considerable impact for future research in the field of antimicrobials.’

Beyond tumour suppression: p53 is a key regulator of vertebrate regeneration

Salamanders are the champions of regeneration. Unlike mammals, these organisms are able to regenerate an impressive repertoire of body structures, including spinal cord, heart, brain and entire limbs. Understanding how salamanders regenerate complex structures is of great biological interest because it can provide insights into fundamental cellular processes as well as eventually teaching us how to stimulate regeneration in humans. Recent research from ISMB researchers Max Yun, Phillip Gates and Jeremy Brockes has uncovered a new molecular mechanism for controlling the process of salamander regeneration, dependent on the tumour suppressor p53.

The authors sought to understand the molecular mechanisms that control regeneration using the salamander limb as their system. Limb regeneration depends on the reprogramming of differentiated cells within the mature tissues. Upon amputation, these cells dedifferentiate and re-enter the cell cycle to proliferate, forming a mound of progenitor cells called a blastema. These cells can then undergo a redifferentiation process that leads to the restoration of the limb. What are the molecular mechanisms underlying the regulation of such critical dedifferentiation-differentiation processes?

Their research, published in the journal PNAS, shows that regulation of p53 is central to the answer. They found that, as regeneration begins, the salamander temporarily downregulates p53 activity enabling the reprogramming of differentiated cells and their re-entry into the cell cycle. Later on, the organism upregulates p53 to trigger redifferentiation as the new limb is formed. The authors were able to show not only that these changes in p53 activity happen but that they are functionally critical for regeneration.


How is this strict temporal regulation achieved? The authors suggest a key role for a p53 dominant negative isoform, Np73, which they found to exhibit an inverse pattern of expression through salamander regeneration compared to p53. When its expression was artificially prolonged the redifferentiation phase of regeneration was delayed. Based on these findings, the authors propose that in salamanders the absence of tumour suppressors that stabilise p53 allows p53 activity to fluctuate (albeit under strict temporal control) in a manner which would not be possible in other species. The control of this fluctuation by regulators such as Np73 enables salamanders to execute the precise dedifferentiation and redifferentiation of adult tissue required for limb regeneration.

This research uncovers a key molecular mechanism controlling differentiation and its reversal in vertebrates. Additionally, it provides a new perspective on the functions of the key tumour suppressor p53. It reveals how subtle regulation of p53 is critical to a process which must orchestrate dedifferentiation, proliferation and redifferentiation whilst maintaining strict genomic integrity. Hence, the interplay between p53’s functions in tumour suppression, cell plasticity and development don’t have to be trade-offs. Strict p53 temporal regulation, revealed here in one remarkable species, is permissive for regeneration but retains its acute tumour resistance, a well-established characteristic of this process.

Structural and Energetic Basis of Folded-Protein Transport by the FimD Usher

Geibel S., Procko E., Hultgren S.J., Baker D., Waksman G. Nature 496, 243–246, doi:10.1038/nature12007

Published this month in Nature, Prof Gabriel Waksman, his group member Dr Sebastian Geibel and their collaborators have revealed the structural and energetic process by which bacteria transport pili across their outer membrane. Pili are a key target for a new generation of antibiotics, as without them bacteria are unable to group together and to stick to human cells causing infection.

In the cystitis bacteria, pili enable bacteria to group together and then to attach to the wall of the bladder. The bladder cells then engulf the bacteria and this makes antibiotic treatment very difficult. Once inside the bladder cells the bacteria can lie dormant, making recurrent infections common. It is believed that a new generation of antibiotics could be developed to disrupt the process of pili biogenesis, making the condition easier to treat.

Previous research by the ISMB members uncovered how pili biogenesis is initiated by the protein FimD – an usher in the outer cell wall. FimD is responsible for recruiting subunits, assembling them into a pilus, and secreting the pilus as it is being formed. From this work, the team was able to develop a model for the way the usher carry out all these tasks. The latest research, funded by the Medical Research Council, provides experimental proofs for the model proposed before and shows how, once the subunits have been assembled, the new pilus is secreted from inside the FimD protein to the exterior, via a pore, across the outer bacterial membrane.

The team has now revealed that as the pilus is assembled, the first subunit (FimH) engages with the usher and undergoes structural changes. This creates the necessary energy for this subunit, which forms the tip of the pilus, to displace the plug which is normally found inside the pore, and to pass through the pore itself. As subsequent subunits of the pilus pass into the pore, other structural changes in FimH prevent the pilus retreating back through the pore.
The team has also revealed that within the usher’s pore there are specific binding sites for the tip and the subsequent subunits of the pilus. These binding sites are 180 degrees apart within the barrel of the pore (facing each other); so that the pilus is held in a central position as it emerges from the pore, facilitating its exit.  Furthermore, it has n that as the pilus passes through the pore it follows a rotational and translational path, enabling subsequent subunits to continue being added within the usher as the tip emerges, while the pilus is still held in a central position.

"For the first time we have been able to see the structural and energy pathways via which the FimD usher protein facilitates the transport of the newly assembled pilus across the outer membrane of the bacteria. This process is a key target for the development of new antibiotics, as if biogenesis of new pili can be disrupted the bacteria will be unable to attach themselves to human cells and infection will be much less likely. “We have been working for a number of years to try and understand the process of pili biogenesis and an understanding of this process takes us a step closer to the development of new antibiotics which will successfully treat cystitis – a common and extremely painful condition, as well as other bacterial infections.”

Dr Adeline Goulet paper selected as Article of the Month by the French Society of Biochemistry and Molecular Biology

April 2013

A study by Dr Adeline Goulet in the Moores group, “The structural basis of force generation by the mitotic motor kinesin-5”, has recently been published in The Journal of Biological Chemistry (Dec 28 (2012); 287(53): 44654-66.)

Kinesin-5 motors are important in eukaryotes for the formation and maintenance of the microtubule-based, bipolar mitotic spindle. Kinesin-5s have also been of great interest as novel targets for anti-cancer therapies: kinesin-5-specific drugs block mitosis and are in phase II clinical trials. By using cryo-electron microscopy and sub-nanometre resolution structure determination, Goulet et al have visualised ATP-dependent conformational changes in the kinesin-5 motor domain while bound to its microtubule tracks. These structures provide insight into the mechanism of force generation by kinesin-5s. They also present evidence for auto-regulation of motor activity by a kinesin-5-specific loop that acts as a competitive inhibitor to ATP binding. Future work will be directed at understanding the significance of this finding in the context of the mitotic spindle.

The paper has been selected as Article of the month (April) of the Société Française de Biochimie et de Biologie Moléculaire ( This work is an inter-disciplinary collaboration with Professor Steve Rosenfeld at the Cleveland Clinic, and was funded by the BBSRC.

Welcome to Prof David Lomas

New Dean of Medical Sciences and ISMB Core Member

The ISMB is delighted to welcome as an ISMB member Prof. David Lomas PhD, ScD, FRCP, FMedSci.
David is the new Dean of the Faculty of Medical Sciences at UCL. His research interests are in understanding the mechanisms of diseases caused by protein misfolding, in particular the serpinopathies, in order to develop novel therapies.

David chairs the MRC Population and Systems Medicine Board, the Respiratory Therapy Area Board at GlaxoSmithKline, and is Chair of the Research Committee and Trustee of the British Lung Foundation. More recently he has chaired the strategic priorities working group for the NHS 100,000 genome project. David has strong experience in applying structural, molecular, cell and computational biology techniques to address unmet clinical needs. Such interface work is increasingly important but it can be challenging for clinicians and scientists, who often work in isolation from each other, to bridge successfully. He is very keen to facilitate such cross-talk between researchers in the ISMB and UCL-affiliated clinicians. Examples of this might include arranging access to relevant ex vivo clinical samples to further test hypotheses supported by in vitro data, or discussing relevant clinical applications of a novel technology. David is happy to be contacted with ideas for such interactions ( They fit within his broader strategy whereby UCL’s internationally prestigious hospitals will actively partner with new (and existing) world-class scientific institutes to optimise biomedical research at all levels.

A nanomachine for getting proteins into working shape

Clare et al., ATP-Triggered Conformational Changes Delineate Substrate-Binding and -Folding Mechanics of the GroEL Chaperonin. Cell (2012), doi:10.1016/j.cell.2012.02.047

Researchers at the ISMB have analysed thousands of images to recreate the elaborate movements of a protein “pot” that encapsulates other proteins and helps them find the right structure and remain healthy when exposed to stresses, e.g. elevated temperature or toxins such as alcohol.

Every cell has a variety of proteins known as molecular chaperones, which, as the name suggests, specialise on the guidance and protection of the innocent and vulnerable among their fellow proteins and shield them from undesirable interactions. Among these, one of the best studied is the bacterial GroEL-GroES system which takes the shape of two cylindrical pots glued back-to-back (each pot is a ring of seven molecules of GroEL) and a matching pair of lids (each made of a ring of seven molecules of GroES).

Previous research had shown that partially structured protein molecules undergo cycles of binding and release inside the pot until they emerge with the correct structure (identified by the fact that its surface no longer displays any of the oil-like water-repellent chemical groups that should be tucked away in the core of the structure). Structural analysis had also shown dramatic differences between the conformations that the GroEL molecules in the sides of each pot adopt in various functional states, e.g. with and without a protein inside, or with and without the GroES lid. Just how these different shapes interconvert remained a mystery, however.

Now Helen Saibil and her coworkers at Birkbeck College, collaborating with Art Horwich at Yale University and using the automated electron microscopy facility at the Scripps Research Institute in La Jolla, have crowned their long-running structural work on molecular chaperones using electron microscopy at very low temperatures (cryo-EM) by combining a large number of snapshots of GroEL-GroES complexes to build a movie that shows a plausible way in which the seven subunits of each pot tilt, expand, and twist to change their shapes during the functional cycle of this chaperone.

The movies (which will be available as supplementary information on the Cell web site) show several distinct phases of coordinated movement carried out by the seven subunits in the same ring, much like a synchronised swimming team. The movements they describe suggest how the subunits can first bind the protein inside the cavity, potentially stretch it to undo incorrectly folded molecules, and then release it to allow it to find its own structure in the aqueous environment inside the pot. If the protein still displays water-repellent patches after it is released back into solution, it will bind to a new GroEL ring and run through the cycle again. Once it is correctly folded it will be stable in the cell environment and will carry out its biological function.

“The operation of chaperone machines is of fundamental importance in the processes that underlie protein quality control and repair,” says Helen Saibil. “It is these functions that decline at different rates in different people during ageing. If we can understand the details of how these machines work and what determines their level of activity, we may arrive at a better understanding of age-related, degenerative diseases for which effective treatments are currently lacking.”

Dr Carolyn Moores' Group Receives an MRC Programme Grant
January 2012

The Moores group has recently been awarded an MRC Programme Grant. The goal of the research programme is reconstitution of the microtubule-based cellular machinery that is essential for neurogenesis, neuronal migration and differentiation. In particular, the group will investigate the activities of the essential doublecortin family of microtubule associated proteins. The regulatory mechanisms of doublecortin family members will be probed using biochemistry, biophysics and structure determination using cryo-electron microscopy. Molecular findings will be placed in a cellular context by visualising the microtubule cytoskeleton within neurons using cryo-electron tomography. This interdisciplinary research will provide insight into the mechanisms and functions of a family of essential neuronal proteins with important implications for human health.


Dr Finn Werner recipient of a Wellcome Trust Investigator Award
January 2012

Dr Finn Werner from the ISMB has received a Wellcome Trust Investigator Award (WT096553/Z/11/Z) for carrying out 'An integrated study of RNA polymerase transcription'. Finn's RNAP laboratory will continue to explore the molecular mechanisms of transcription - in particular of complex RNA polymerases - by using biochemical, biophysical and structural approaches. In addition the WT investigator award allows the expansion of the RNAP lab into new disciplines such as genetics and systems biology, including transcriptomics and whole genome occupancy studies. The award encompasses £1.4M and will fund three postdoctoral positions for a duration of five years (2012-2017). The systems biology will be explored in collaboration with Jürg Bähler from the GEE department of UCL. Part of the ample funds that are included in the grant cover costs for the equipment of a small growth and fermentation facility for hyperthermophilic Archaea at UCL, in particular Sulfolobus acidocaldarius.


Structural model of the RNAP elongation complex. The RNAP (grey) -bound transcription elongation factor Spt4/5 (wheat/red-green) has recruited ribosomal protein S10 (blue) that in conjunction with the mRNA transcript (turquoise) is ready to recruit the initiating ribosome to facilitate efficient coupling of transcription and translation. Double stranded template DNA is highlighted in purple.

The Initiation Factor TFE and the Elongation Factor Spt4/5 Compete for the RNAP Clamp during Transcription Initiation and Elongation (27th July 2011)
Dina Grohmann and Finn Werner (UCL, Research Department of Structural and Molecular Biology) have discovered a novel mechanism by which basal transcription factors compete for the binding to RNA polymerase (RNAP) during the transcription cycle. This work identifies a flexible module of the RNAP called the clamp as valuable real estate for factor function.


TFIIE and the archaeal homolog TFE enhance DNA strand separation of eukaryotic RNAPII and the archaeal RNAP during transcription initiation by an unknown mechanism. We have developed a fluorescently labeled recombinant M. jannaschii RNAP system to probe the archaeal transcription initiation complex, consisting of promoter DNA, TBP, TFB, TFE, and RNAP. We have localized the position of the TFE winged helix (WH) and Zinc ribbon (ZR) domains on the RNAP using single-molecule FRET. The interaction sites of the TFE WH domain and the transcription elongation factor Spt4/5 overlap, and both factors compete for RNAP binding. Binding of Spt4/5 to RNAP represses promoter-directed transcription in the absence of TFE, which alleviates this effect by displacing Spt4/5 from RNAP. During elongation, Spt4/5 can displace TFE from the RNAP elongation complex and stimulate processivity. Our results identify the RNAP “clamp” region as a regulatory hot spot for both transcription initiation and transcription elongation.

Dr Chris Kay admitted as a Fellow of the Royal Society of Chemistry (24 March 2011)

Since his appointment in 2006, Chris Kay (UCL SMB) has established an interdisciplinary Electron Paramagnetic Resonance (EPR) Facility at UCL that is bringing this methodology to research as diverse as oxidative stress and aging due to reactive oxygen species (known as ROS) in medicine, structural biology where EPR complements X-ray crystallography, and characterisation of novel materials including thin films for organic solar cells and quantum information processing. A CIF investment through the BEAMS School enabled outdated equipment from the Departments of Chemistry and Biology to be upgraded and a state of the art pulsed EPR spectrometer to be purchased from Bruker. The Faculty of Life Sciences provided a refurbished space to house all three instruments which is located on the main campus in the Darwin Building.

Recent publications include the first demonstration that EPR could be used to precisely measure distances between protein-bound copper ions (Kay et al (2007) J. Am. Chem. Soc. 129 4868), characterisation of radical activation of carbon nanotubes (Menzel et al. (2010), Chemical Science 1 603), a FRET and EPR strudy of RNA-Binding to Archaeal RNA Polymerase Subunits F/E (Grohmann et al. (2010) J. Am. Chem. Soc. 132 5954), and the observation of exceptionally long relaxation times of bismuth dopants in silicon (Morley et al. (2010) Nature Materials 9 725).

RNAP laboratory develops novel theory on evolution of transcription (9 February 2011)

Finn Werner and Dina Grohmann from the RNAP laboratory at UCL SMB have developed a novel theory on the evolution of transcription regulation – the ‘elongation first hypothesis’ 1. By studying the structure and function of the engine of transcription, RNA polymerase (RNAP), and the factors that orchestrate its activities they conclude that the ancestral RNAP of the last universal common ancestor (LUCA) of all extant life was regulated during the elongation phase of the transcription cycle. This theory represents a paradigm shift in the field since according to textbook dogma RNAP - and thereby gene expression - is principally controlled at the level of transcription initiation.

This year a team of three students from UCL has won a Silver medal at the 2009 iGEM competition. The UCL iGEM team was composed of one of our final year biochemists, Xiang Chen, and two Biochemical Engineering students, Anike Akinrinlade and Axel Nystrom. They competed with 110 other teams from all over the world, see: Their success is even more stunning when one considers that the majority of teams often have 10 or more students. The UCL iGEM team are the ‘Stress Busters’ and they designed in vivo detectors of stress for E. coli that could monitor and report on shear stress and pH stress in real time for cells growing in fermenters.
They have submitted several new BioBricks to the BioBrick registry

They divided their time between John Wards lab on the ground floor in SMB for their molecular biology work and the Advanced Centre for Biochemical Engineering for their fermentations. Dr Darren Nesbeth helped them in the lab and Darren has recently given up his position as a postdoc supervised by John Ward and Eli Keshavarz-Moore (Biochemical Engineering) to become a Lecturer in Synthetic Biology in the Biochem. Eng. Department, UCL.

What is iGEM?

iGEM stands for International Genetically Engineered Machines and is an undergraduate Synthetic Biology competition that has now been running since 2003. Students have access to the toolkit of biological parts at the Registry of Standard Biological Parts and are encouraged to construct new parts, called BioBricks, to add to the repository. The iGEM teams have from January till September to plan, design and implement their project. The kinds of projects that have been done by this years iGEM teams can be seen at

Well Done ‘Stress Busters’ and all who helped aided and assisted.

A new blood-based breast cancer detection by diagnostic proteomics

A new blood based breast cancer detection test is reported in the Journal of Proteome Research by Prof Jasminka Godovac-Zimmermann, of University College London, who collaborated with international group, which included scientists from the universities of Pennsylvania and Pittsburgh and the company BioTraces, Inc in Herndon, Virginia. The group has developed novel biomarker panels which include tissue-specific cancer biomarkers as well as cytokines and angiogenic factors. The new test based on ultra-sensitive method of immunoassay using multi-photon-detection increases sensitivity by 200- to 1000-fold (1 femtogram/ml). This has allowed the measurement of cancer biomarkers with very low concentrations in blood that could not be measured for full patient cohorts with conventional immunoassays. The new method revealed that patient to patient variations in the concentrations of individual biomarkers in blood can extend over many orders of magnitude (up to six) and that the distributions of biomarker concentrations over patient cohorts are non-Gaussian. A new method of data analysis which correlate abundances of multiple, different biomarkers have also been developed to deal with such data sets. Among 345 women the blood test picked up 95% of cancers, making it much more sensitive than existing tests. The developed blood test can reveal if a woman has breast cancer and at an earlier stage than is possible with currently available tests.

16 March 2006: ISMB core member Carolyn Moores wins award at House of Commons event for National Science Week. You can view her winning poster here.

Dr Carolyn Moores is this year’s winner of the prestigious De Montfort Medal for excellence in science communication. Dr Moores, from Birkbeck’s School of Crystallography, competed with her peers at the House of Commons in a research presentation for National Science Week for Britain’s top younger scientists, engineers and technologists on Monday 13 March.

Dr Moores, who is a BBSRC David Phillips Fellow, says: “I was extremely surprised but delighted to receive this award. All the presentations at the event were excellent. I learnt a lot from talking to the other presenters, so I am sure that the judges’ decision was very difficult.”

Describing her award-winning work, Dr Moores says: “The human brain is built from billions of specialised cells called neurons. During brain development, they undertake an amazing journey so they can get to the right place at the right time and make the correct connections. Various molecules are needed to help neurons find their way. In particular, components of the cytoskeleton - the skeleton of cells - are centrally involved. Mutations in the doublecortin gene severely affect this migration and cause the disease lissencephaly in humans, resulting in mental retardation and epilepsy. Therefore, doublecortin, a component of the microtubule cytoskeleton, is essential but its exact function is unclear.”

To understand its function better, Dr Moores and her team have used a number of experimental approaches that include biochemistry and electron microscopy. “Using electron microscopy, we are able to calculate a molecular map of doublecortin bound to microtubules and this helps us to understand how they work together. Our results help to explain why doublecortin is an essential molecule during brain development.”

She continues: “I’m lucky to be part of a great team of scientists working in this field of research and we all rely on and learn from each other. It is exciting for our work to be recognised and I am proud to be able to raise the profile of research at Birkbeck. It was a privilege to present my work at the Houses of Parliament – it’s important to take every opportunity to talk about what we do and why we do it to a non-scientific audience.”

This is the eighth year of National Science Week, where Britain's younger researchers present posters at Westminster on leading-edge science, engineering, medicine and technology research and compete for national awards. These events are very popular with researchers, MPs, peers and other visitors and help engender better dialogue among MPs, early-stage researchers and UK's research communities.
