Role of the Carboxylate in Enzyme-Catalyzed Decarboxylation of Orotidine 5′-Monophosphate: Transition State Stabilization Dominates Over Ground State Destabilization

[Image: see text] Kinetic parameters k(ex) (s(–1)) and k(ex)/K(d) (M(–1) s(–1)) are reported for exchange for deuterium in D(2)O of the C-6 hydrogen of 5-fluororotidine 5′-monophosphate (FUMP) catalyzed by the Q215A, Y217F, and Q215A/Y217F variants of yeast orotidine 5′-monophosphate decarboxylase (...
