Orotidine 5'-phosphate
UMP + CO2
the remote 5'-phosphate group of the substrate activates the enzyme 240 millionfold, the activation corresponds to an intrinsic binding energy of 11.4 kcal/mol. This intrinsic binding energy is used to allow interactions both near the N-terminus of the active site loop and across the domain interface that stabilize both the Ec-S and Ec-S* complexes relative to the Eo-S complex

-
catalytic mechanism, the remarkable catalytic power is almost exclusively achieved via ground state destabilization of the reactive part of substrate, which is compensated for by strong binding of the phosphate and ribose groups, and to a lesser extend via transition state stabilization, enzyme/active site structure, mode of substrate binding
-
?
Orotidine 5'-phosphate
UMP + CO2
-
mechanism involving an equilibrium pre-protonation of orotidine 5'-phosphate C5 by the catalytic Lys-72 residue that greatly reduces the barrier to subsequent decarboxylation, Lys-72 is not critical for substrate binding

?
Orotidine 5'-phosphate
UMP + CO2
-
mechanism, enzyme conformation is more distorted in the reactant state than in the transition state, the energy released from conformation relaxation provides the predominant contribution to the rate enhancement, the active site consists of a network of charged residues Lys-42, Asp-70, Lys-72, Asp-75b

?
Orotidine 5'-phosphate

crystal structures with ligand anlogues. Enzyme can distort the bond between the aromatic ring of a ligand and its C6 substituent, regardless of the latter's charge or size. The distortion contributes 3.7 kcal/mol to the catalysis. In their respective complexes, 6-methyl-UMP displays significant distortion of its methyl substituent bond, 6-amino-UMP shows the competition between the K72 and C6 substituents for a position close to D70, and the methyl and ethyl esters of orotidine 5'-monophosphate both induce rotation of the carboxylate group substituent out of the plane of the pyrimidine ring. In addition, the bond between the carboxylate group and the pyrimidine ring is distorted
