Studying protein conformation using a new cyclic ion mobility mass spectrometry (cIMMS) device

Dr Konstantinos Thalassinos

We are the first group to publish a paper on how a new cyclic ion-mobility mass-spectrometry (cIMMS) device, manufactured by Waters, can be used to probe protein structure and dynamics. In particular, the tandem ion mobility capabilities of the instrument allow us to probe in very fine detail protein unfolding pathways and for the first time to do so for co-existing and interconverting conformers. We are now using this technology to study proteins involved in protein misfolding diseases such as human amyloid islet polypeptide.

The paper is:

New, giant bacterial virus found in human gut

A new giant virus that infects bacteria commonly found in the human gut has been discovered by an international team led by researchers from UCL including Professor Joanne Santini, and UC Berkeley.

The new ‘megaphage’ called ‘Lak’ is the same size as some bacteria and is the biggest ever reported phage found in the human gut.

A study published in Nature Microbiology describes the discovery of Lak phage and reports that they specifically infect bacteria called Prevotella, which live in all people but most notably those who have a diet high in fibre and low in fat.

Prevotella is also associated with upper respiratory tract infections and is prevalent in periodontal disease, which means the new megaphage may open up the development of new phage-based treatments for infections caused by Prevotella.
