CC   -!- FUNCTION: Catalyzes the oxidation of 5,10-
CC       methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and
CC       then the hydrolysis of 5,10-methenyltetrahydrofolate to 10-
CC       formyltetrahydrofolate (By similarity).
CC   -!- CATALYTIC ACTIVITY: 5,10-methylenetetrahydrofolate + NADP(+) =
CC       5,10-methenyltetrahydrofolate + NADPH.
CC   -!- CATALYTIC ACTIVITY: 5,10-methenyltetrahydrofolate + H(2)O = 10-
CC       formyltetrahydrofolate.
CC   -!- PATHWAY: One-carbon metabolism; tetrahydrofolate pathway.
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- SIMILARITY: Belongs to the tetrahydrofolate
CC       dehydrogenase/cyclohydrolase family.
