CC   -!- FUNCTION: Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to
CC       5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10-
CC       methenyltetrahydrofolate to 10-formyltetrahydrofolate.
CC       {ECO:0000255|HAMAP-Rule:MF_01576}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + NADP(+) = 5,10-
CC         methenyltetrahydrofolate + NADPH; Xref=Rhea:RHEA:22812,
CC         ChEBI:CHEBI:15636, ChEBI:CHEBI:57455, ChEBI:CHEBI:57783,
CC         ChEBI:CHEBI:58349; EC=1.5.1.5; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01576};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5,10-methenyltetrahydrofolate + H2O = (6S)-10-
CC         formyltetrahydrofolate + H(+); Xref=Rhea:RHEA:23700,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57454,
CC         ChEBI:CHEBI:57455; EC=3.5.4.9; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01576};
CC   -!- PATHWAY: One-carbon metabolism; tetrahydrofolate interconversion.
CC       {ECO:0000255|HAMAP-Rule:MF_01576}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01576}.
CC   -!- SIMILARITY: Belongs to the tetrahydrofolate
CC       dehydrogenase/cyclohydrolase family. {ECO:0000255|HAMAP-Rule:MF_01576}.
