Biophysical Chemistry

Structural & Mechanistic Biology, Protein Dynamics & Allostery The main research interests of the lab have been focused on the elucidation of the molecular and mechanistic basis of a wide range of important biological phenomena. Our current and future efforts are directed towards understanding how central biological processes, such as transcription regulation, protein translocation and secretion, cell signaling, and protein folding take place. We strongly believe that a detailed characterization of biomolecular interactions necessarily involves investigation of the inter-relationship between function, structure, dynamics, kinetics and energetics of a system. Towards this challenging goal, we employ state-of-the-art NMR spectroscopy methodologies complemented by many other biochemical and biophysical techniques. NMR spectroscopy in particular is a very powerful methodology that allows the study of the three-dimensional structure of biomolecules in semi-physiological conditions. Furthermore, NMR spectroscopy can provide a unique insight into the dynamic aspects of the macromolecules and their interaction with ligands over time. Application of these methodologies in our lab has already resulted in very exciting and novel information.
