CC -!- FUNCTION: Catalyzes the reductive methylation of 2'-deoxyuridine-5'-
CC monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while
CC utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor,
CC and NADPH and FADH(2) as the reductant. {ECO:0000256|HAMAP-
CC Rule:MF_01408}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + dUMP + H(+) +
CC NADPH = (6S)-5,6,7,8-tetrahydrofolate + dTMP + NADP(+);
CC Xref=Rhea:RHEA:29043, ChEBI:CHEBI:15378, ChEBI:CHEBI:15636,
CC ChEBI:CHEBI:57453, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349,
CC ChEBI:CHEBI:63528, ChEBI:CHEBI:246422; EC=2.1.1.148;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01408};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01408};
CC Note=Binds 4 FAD per tetramer. Each FAD binding site is formed by three
CC monomers. {ECO:0000256|HAMAP-Rule:MF_01408};
CC -!- PATHWAY: Pyrimidine metabolism; dTTP biosynthesis. {ECO:0000256|HAMAP-
CC Rule:MF_01408}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000256|HAMAP-Rule:MF_01408}.
CC -!- SIMILARITY: Belongs to the thymidylate synthase ThyX family.
CC {ECO:0000256|HAMAP-Rule:MF_01408}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01408}.
