CC -!- FUNCTION: Key enzyme in folate metabolism. Catalyzes an essential
CC reaction for de novo glycine and purine synthesis, and for DNA
CC precursor synthesis. {ECO:0000256|PIRNR:PIRNR000194}.
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|PIRNR:PIRNR000194};
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:PIRNR000194}.
CC -!- SIMILARITY: Belongs to the dihydrofolate reductase family.
CC {ECO:0000256|ARBA:ARBA00009539, ECO:0000256|PIRNR:PIRNR000194}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:GAF02460.1}.
