Research Interests

Protein Biophysics Emphasizing Studies in Living Cells


Research Synopsis

My graduate students and I work in two areas:
High-resolution protein NMR studies in living cells.
Biophysics of tardigrade dessication-tolerance proteins.

We quantified the stability of a model protein complex, the A34F GB1 homodimer, in buffer, Escherichia coli cells and Xenopus laevis oocytes. The complex is more stable in cells than in buffer and more stable in oocytes than E. coli.

 

Water is key to protein structure and stability, yet the relationship between protein–water interactions and structure is poorly understood, in part because there are few techniques that permit the study of dehydrated protein structure at high resolution. Here, we describe liquid-observed vapor exchange (LOVE) NMR, a solution NMR-based method that provides residue-level information about the structure of dehydrated proteins.
