METHYLMALONYL-COA MUTASE, 2-CARBOXYPROPYL-COA INHIBITOR COMPLEX


Overview

X-ray crystal structures of methylmalonyl-CoA mutase in complexes with substrate methylmalonyl-CoA and inhibitors 2-carboxypropyl-CoA and 3-carboxypropyl-CoA (substrate and product analogues) show that the enzyme-substrate interactions change little during the course of the rearrangement reaction, in contrast to the large conformational change on substrate binding. The substrate complex shows a 5'-deoxyadenine molecule in the active site, bound weakly and not attached to the cobalt atom of coenzyme B12, rotated and shifted from its position in the substrate-free adenosylcobalamin complex. The position of Tyralpha89 close to the substrate explains the stereochemical selectivity of the enzyme for (2R)-methylmalonyl-CoA.
