Rapid Protein Dynamics – Tunneling, Catalysis, and Enzyme Design

Steven D. Schwartz
University of Arizona

This talk will focus on our work determining the “reaction coordinate” of enzymatic systems. This is the set of all atomic motions that are both necessary and sufficient for reaction to occur. Reaction in enzymes is an extremely rare event (barrier passage occurs in femtoseconds while turnover is usually on the order of milliseconds,) and so we develop rare event methods to study this problem. We further develop methods to analyze the ensemble of trajectories. We will focus on mechanism, purported tunneling in hydride transfer enzymes, and finally on our recent progress in using these concept to further artificial design.
