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:0000256|HAMAP-Rule:MF_01576}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methenyltetrahydrofolate + H2O = (6R)-10-
CC formyltetrahydrofolate + H(+); Xref=Rhea:RHEA:23700,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:57455,
CC ChEBI:CHEBI:195366; EC=3.5.4.9; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_01576};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(6R)-5,10-methylene-5,6,7,8-tetrahydrofolate + NADP(+) = (6R)-
CC 5,10-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:0000256|HAMAP-
CC Rule:MF_01576};
CC -!- PATHWAY: One-carbon metabolism; tetrahydrofolate interconversion.
CC {ECO:0000256|ARBA:ARBA00004777, ECO:0000256|HAMAP-Rule:MF_01576}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01576}.
CC -!- SIMILARITY: Belongs to the tetrahydrofolate
CC dehydrogenase/cyclohydrolase family. {ECO:0000256|HAMAP-Rule:MF_01576}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
