Coordinated protein-protein interactions (PPIs) play an important role in majority of the biological processes. Studying protein-protein interactions is thus imperative to get a broader view of a biological process. PPIs have also been of special interest in the recent past as they represent important and novel drug targets for future therapeutic applications. A major focus of the research in my lab is to investigate role of PPIs that modulate transcription, electron transport and intercellular communications in bacteria. More ambitious goal is to identify and validate ‘hotspots’ on protein-protein interfaces that could be targeted for drug design. We use X-ray crystallography along with combination of other biophysical/biochemical techniques to reveal high resolution molecular details of proteins and protein-protein complexes and characterize their interactions.
