Eleanor Jayawant

PhD Project

I am working under the supervision of Dr Rebecca Notman and Dr Ann Dixon to study the structure of small oxetane-modified peptides, in collaboration with Professor Mike Shipman (funded by The Leverhulme Trust). I am using molecular dynamics techniques (Notman) to simulate modified and unmodified parent peptides (with and without NMR refinement), and comparing these to my experimental findings obtained using biophysical techniques such as 2D NMR and CD (Dixon).

So far my project has involved two main model systems: a small pentapeptide, which I have worked on both the linear and cyclic forms (to assess the effect of the oxetane modification on cyclisation), and a longer, helical peptide with and without the oxetane modification (to assess the effect of the oxetane on helical structures). I hope to work on a more biologically relevant model system in the coming months.

The NMR experiments I carry out use the high field NMR facilities at Warwick (Bruker Avance II 700 MHz), and I regularly run TOCSY, NOESY and 1H-13C and 1H-15N natural abundance HSQCs. Nuclear Overhauser Effect Spectroscopy (NOESY) experiments provide information about protons near to each other in space, so NOE correlations can be converted to distance restraints, which I impose in my MD simulations.

My MD work uses GROMACS and the CHARMM force field to simulate peptides with and without modifications. For most of my work so far I have been using brute force MD, although I am exploring the possibility of using advanced sampling techiques such as steered MD.

I'm an Associate Member of the Royal Society of Biology (AMRSB) and a member of the Biochemical Society. I regularly demonstrate 2nd and 3rd year chemical biology labs (gel electrophoresis) here at Warwick, as well as the occasional 3rd physical chemistry workshop. In the second year of my PhD I set up a weekly theoretical chemistry seminar series.

When I'm not working on my PhD, I'm a keen amateur baker, and love to experiment in the kitchen! I'm also a novice artist/calligrapher. I enjoy playing board games with friends, and spending time with my two cats.
