X-ray Crystallographic Studies of Reaction Intermediates in Proteins Containing Organic or Metal Co-factors

This research focuses on the dynamics of molecular catalysis, particularly involving novel co-factors and metal ions. The principal tool of the research is macromolecular x-ray crystallography. The project involves freeze trapping catalytic intermediates in the crystal, both anaerobically and aerobically, leading to "snapshots” along the reaction pathways. These can be assembled into "movies of catalysis” at the molecular level. By understanding these reactions in such detail, better drugs can be designed, proteins can be rationally engineered for biotechnological purposes, and chemists can design simpler industrial catalysts to control analogous reactions. Specific topics of interest to this group include structural enzymology involving the co-factor tryptophan tryptophylquinone of methylamine dehydrogenase and dioxygen activation by the copper-containing amine oxidase from yeast.
