1-(beta-D-erythrofuranosyl)-5-fluoroorotic acid
? + CO2
show the reaction diagram
-
truncated analog of the natural substrate orotidine 5'-monophosphate with enhanced reactivity towards decarboxylation. The vinyl carbanion-like transition state is stabilized by 3.5 kcal/mol by interactions with the 5-F substituent. Decarboxylation is activated by exogenous phosphite dianion, but the 5-F substituent results in only a 0.8 kcal stabilization of the transition state for the phosphite-activated reaction

-
truncated analog of the natural substrate orotidine 5'-monophosphate with enhanced reactivity towards decarboxylation. The 4'-CH3 and 4'-CH2OH groups of 5'-deoxy-5-fluoroorotidine and orotidine, respectively, result in identical destabilizations of the transition state for the unactivated decarboxylation of 2.9 kcal/mol. By contrast, the 4'-CH3 group of 5'-deoxy-5-fluoroorotidine and the 4'-CH2OH group of orotidine result in very different 4.7 and 8.3 kcal/mol destabilizations of the transition state for the phosphite-activated decarboxylation

in reaction model phosphodianion binding interactions are utilized to stabilize a rare closed enzyme form that exhibits a high catalytic activity for decarboxylation. The thermodynamic barrier to formation of the productive catalytic complex from the inactive enzyme arises largely from the desolvation of the active site accompanying the conformational change and sequestration of the substrate from bulk solvent. The energetically unfavorable conformational change and desolvation of the active site are paid for by the binding energy available from the formation of strong phosphodianion-protein interactions in the desolvated environment present at the ECS complex. The phosphodianion binding energy is recovered as transition state stabilization via the enhanced electrostatic and hydrogen bonding interactions at the transition state in the desolvated active site

the total transition-state stabilization for decarboxylation of orotidine 5'-phosphate via the UMP vinyl carbanion intermediate exceeds that for the formation of this carbanion by proton transfer from C-6 of UMP to the enzyme by ca.17 kcal/mol. A large portion of the total transition-state stabilization for the decarboxylation of orotidine 5'-monophosphate can be accounted for by stabilization of the enzyme-bound vinyl carbanion intermediate of the stepwise reaction

the inhibitor molecule occupies a part of the active site that overlaps with the phosphate-binding region in the OMP- or UMP-bound complexes. The carboxyl group of the inhibitor causes a dramatic movement of the L1 and L2 loops that play a role in the recognition of the substrate and product molecules

decarboxylation of substrate analog 5'-deoxy-5-fluoroorotidine is activated. Decarboxylation of truncated substrate analog 1-(beta-D-erythrofuranosyl)-5-fluoroorotic acid is activated by exogenous phosphite dianion, but the 5-F substituent results in only a 0.8 kcal stabilization of the transition state for the phosphite-activated reaction

orotidine 5'-phosphate
Methanothermobacter thermautotrophicum
-
the 5'-phosphate group of the substrate activates the enzyme 240000000fold. The binding of orotidine 5'-monophosphate is accompanied by a conformational change of the enzyme from an open, inactive conformation to a closed, active conformation. 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 are enforced. The activation is equivalently described by an intrinsic binding energy of 11.4 kcal/mol. The residues that directly contact the 5'-phosphate group, participate in a hydrophobic cluster near the base of the active site loop that sequesters the bound substrate from the solvent, or that form hydrogen bonding interactions across the interface between the mobile and fixed half-barrel domains of the (beta/alpha)8-barrel structure. The data support a model in which the intrinsic binding energy provided by the 5'-phosphate group is used to allow interactions both near the N-terminus of the active site loop and across the domain interface that stabilize the complexes of the enzyme in the active closed conformation with the substrate or with the substrate intermediate with the destabilized carboxylate group relative to the complex of the enzyme in the open inactive conformation with the substrate

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
