Research

The Boehr lab is interested in the role of protein dynamics in enzyme function, coordination and regulation.  There is still controversy within the enzyme field concerning the importance of protein motion to enzyme function, which can impact practical applications of biochemistry like protein engineering and structure-based drug design.  We believe a multi-disciplinary approach combining in vivo assays and biochemical/biophysical approaches, will be necessary to resolve the connections between enzyme activity, protein structure/dynamics and biological function.  One of our main tools to analyze enzyme dynamics is nuclear magnetic resonance (NMR) that allows site-specific structural and dynamic detail across 10¹⁷orders of magnitude (10^-12 - 10⁵ seconds).  The Boehr lab combines NMR studies with more traditional enzyme techniques (e.g. steady-state enzyme kinetics, site-directed mutagenesis, protein folding, directed evolution) to elucidate the connections between enzyme function, structure and dynamics.  We are currently focused on enzymes involved in viral and bacterial pathogenesis.  We believe such studies guide us in making rational decisions regarding rational drug and/or vaccine design.  These studies will also offer us more insight into the molecular evolution of protein function, structure and dynamics.
