Spectroscopic studies on two pyranopterin molybdenum enzymes, sulfite oxidase and xanthine oxidase, have been used to evaluate the results of detailed bonding calculations and provide insight into the reductive half reaction of these enzymes. Specifically, the nature of the reaction coordinate with respect to substrate oxidation appears to be under orbital control, with the inherent electronic structure of the active site playing a key role in the reactivity of these metalloenzymes.
