CC   -!- FUNCTION: Catalyzes the reduction of dihydromonapterin to
CC       tetrahydromonapterin. Also has lower activity with dihydrofolate.
CC       {ECO:0000250|UniProtKB:P0AFS3}.
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         Evidence={ECO:0000250|UniProtKB:P0AFS3};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=7,8-dihydromonapterin + H(+) + NADPH = 5,6,7,8-
CC         tetrahydromonapterin + NADP(+); Xref=Rhea:RHEA:34847,
