Enzyme studies for biocatalysis and other applications

Enzymes are of great interest to our group, not only for their involvement in diseases but also for their unequalled catalytic properties. Indeed enzymes are often enantio-, chemo-, and regio-selective across a wide range of reactions under mild conditions. Yet our understanding of these superior catalysts is only superficial. For example, allostery and cooperativity, which play important roles in biological systems, are only poorly defined. We propose here to study different enzymes, and harness their catalytic abilities for biocatalyis and other applications. The enzymes of interest are from two groups: 1) some acetyltransferases, phosphoryltransferases and adenylyltransferases which show novel allosteric behavior; and 2) P450 enzymes which show complex cooperative behavior and catalyze difficult oxidation reactions at inactivated C-H bonds.
