CC -!- FUNCTION: Bifunctional enzyme. Involved in de novo dTMP biosynthesis.
CC Key enzyme in folate metabolism. Can play two different roles depending
CC on the source of dihydrofolate: de novo synthesis of tetrahydrofolate
CC or recycling of the dihydrofolate released as one of the end products
CC of the TS catalyzed reaction. Catalyzes an essential reaction for de
CC novo glycine and purine synthesis, DNA precursor synthesis, and for the
CC conversion of dUMP to dTMP. {ECO:0000256|ARBA:ARBA00024992}.
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|ARBA:ARBA00001707};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6S)-5,6,7,8-tetrahydrofolate + NADP(+) = 7,8-dihydrofolate +
CC H(+) + NADPH; Xref=Rhea:RHEA:15009, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57451, ChEBI:CHEBI:57453, ChEBI:CHEBI:57783,
CC ChEBI:CHEBI:58349; EC=1.5.1.3;
CC Evidence={ECO:0000256|ARBA:ARBA00001315};
CC -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; 5,6,7,8-
CC tetrahydrofolate from 7,8-dihydrofolate: step 1/1.
CC {ECO:0000256|ARBA:ARBA00004903, ECO:0000256|PIRNR:PIRNR000389}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the thymidylate
CC synthase family. {ECO:0000256|ARBA:ARBA00006900,
CC ECO:0000256|PIRNR:PIRNR000389}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the dihydrofolate
CC reductase family. {ECO:0000256|ARBA:ARBA00010176,
CC ECO:0000256|PIRNR:PIRNR000389}.
