MORPHINONE REDUCTASE
Overview
The crystal structure of the NADH-dependent bacterial flavoenzyme, morphinone reductase (MR) has been determined at 2.2-A resolution in, complex with the oxidizing substrate codeinone. The structure reveals a, dimeric enzyme comprising two 8-fold beta/alpha barrel domains, each bound, to FMN, and a subunit folding topology and mode of flavin-binding similar, to that found in Old Yellow Enzyme (OYE) and pentaerythritol tetranitrate, (PETN) reductase. The subunit interface of MR is formed by interactions, from an N-terminal beta strand and helices 2 and 8 of the barrel domain, and is different to that seen in OYE. The active site structures of MR, OYE, and PETN reductase are highly conserved reflecting the ability of, these enzymes to catalyze "generic" reactions such as the reduction of, ...
