Young Entrepreneur Scheme (YES) success

Natasha Rhys, Tom Dixon, Joe Bluck, Sarah-Beth Amos and Alex Skates in Nottingham

In October, Natasha and Tom were part of an Oxford-based team (pictured above) for the Industrial strategy workshop for the  Young Entreprenuers Scheme (YES) competition in Nottingham.  Their team was selected as one of two teams to be advanced to the final competition at the Royal Society in December.  Well done all!

Ri Friday evening discourse
In February, Sylvia gave a Friday evening discourse at the Royal Institution of Great Britain about the group's work into water's role in protein and peptide folding.  The video of the talk is available on the Ri YouTube Channel.


Part II leaving dinner
In May we said goodbye to Part II students, Imogen Duffy and Rachel McCann who have just completed and defended their MBiochem dissertations! We will miss you in the lab - goodbye and good luck.

New paper published Salt interactions in solution prevent urea from direct association with a peptide backbone

Nicola, in collaboration with Chris Lorenz and Anna Genina of King's College London, has just published a paper on the influence of co-solutes on urea-caused protein denaturation in The Journal of Physical Chemistry B.  This study shows that direct urea contacts to the model peptide KGPGK are obstructed by salt contacts and, conversely, urea lowers charged interactions of the salt molecules with the peptide or each other.

These results shed light on the complex interaction between stabilizing and destabilizing effects of co-solutes on protein folding. Specifically, it might unify existing theories of direct and indirect urea-caused protein denaturation. At higher salt concentrations and low urea concentration urea appears to influence co-solutes around the peptide backbone while at higher urea concentrations, there is a direct hydrogen bonding between urea and peptide.

g(r) database
We have a database for neutron diffraction data from liquids from our investigations, where we have uploaded both RDFs (g(r)s) and S(Q)s from our recent publications here.  If you are interested in adding some published data to our current data base, and we hope you are, please contact Sylvia at
