The binding of a ligand to orotidine 5'-monophosphate decarboxylase (OMPDC) is accompanied by a conformational change from an open, inactive conformation (E(o)) to a closed, active conformation (E(c)). As the substrate traverses the reaction coordinate to form the stabilized vinyl carbanion/carbene intermediate, interactions that destabilize the carboxylate group of the substrate and stabilize the intermediate (in the E(c)·S(‡) complex) are enforced ...
