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 and
CC reductant in the reaction, yielding dihydrofolate (DHF) as a by-
CC product. This enzymatic reaction provides an intracellular de novo
CC source of dTMP, an essential precursor for DNA biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_00008}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + dUMP = 7,8-
CC dihydrofolate + dTMP; Xref=Rhea:RHEA:12104, ChEBI:CHEBI:15636,
CC ChEBI:CHEBI:57451, ChEBI:CHEBI:63528, ChEBI:CHEBI:246422;
CC EC=2.1.1.45; Evidence={ECO:0000256|HAMAP-Rule:MF_00008};
CC -!- PATHWAY: Pyrimidine metabolism; dTTP biosynthesis. {ECO:0000256|HAMAP-
CC Rule:MF_00008}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_00008}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00008}.
CC -!- SIMILARITY: Belongs to the thymidylate synthase family. Bacterial-type
CC ThyA subfamily. {ECO:0000256|HAMAP-Rule:MF_00008}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00008}.
