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|ARBA:ARBA00025067,
CC 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,
