5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP

-
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP
O2 and methylenetetrahydrofolate compete for the reduced enzyme after dUMP binding. dUMP enhances the rate of the oxidative half reaction and while the oxidase reaction is faster than the reaction with methylenetetrahydrofolate, this cofactor slows down the consumption of NADPH in the presence of O2 in accordance with substrate competition. dUMP, the substrate of the oxidative half reaction does not affect the reductive half reaction. In the absence of the second substrate methylenetetrahydrofolate, dUMP enhances the reaction of molecular oxygen with the reduced enzyme
