Biophysics, NMR Spectroscopy, Protein and Ligand Dynamics
The Peng Lab works at the interface of the physical and biological sciences to illuminate the role of bio-molecular dynamics in molecular recognition and evolution.
Our main experimental tool is multi-dimensional NMR. We focus on both methods development, and applications to several proteins of therapeutic interest. Our long term interests include: (i) getting a fundamental understanding of signal transduction and protein evolution that includes conformational ensembles and dynamics. This has relevance for understanding protein-protein interaction networks and drug resistance; (ii) new methods for including flexibility information in iterative drug design. We complement our NMR studies with molecular dynamics calculations, protein biochemistry, and collaborations with groups focused on medicinal chemistry.
