Most of our projects are examining the chemistry of phosphoryl and sulfuryl esters. These compounds have great importance in biological systems, where their hydrolysis and their formation are catalyzed with remarkable efficiency by enzymes at rates millions of times (or more) faster than the analogous uncatalyzed reactions. Our research seeks to understand this chemistry, and how enzymes achieve these remarkable rate accelerations.
