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 (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6S)-5,6,7,8-tetrahydrofolate + NADP(+) = 7,8-dihydrofolate +
CC         NADPH + H(+); Xref=Rhea:RHEA:15009, ChEBI:CHEBI:15378,

CC         ProRule:PRU00660};
CC   -!- PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; 5,6,7,8-
CC       tetrahydrofolate from 7,8-dihydrofolate: step 1/1.
CC   -!- SIMILARITY: Belongs to the dihydrofolate reductase family.
CC       {ECO:0000305}.
