Comments [?]

Function Catalyzes the reductive methylation of 2'-deoxyuridine-5'-monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor, and NADPH and FADH(2) as the reductant.
Catalytic activity RHEA:29043: (6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + dUMP + H(+) + NADPH = (6S)-5,6,7,8-tetrahydrofolate + dTMP + NADP(+)
Cofactor FAD synthase) domain
