Submitted (APR-2007) to the EMBL/GenBank/DDBJ databases.

Comments

FUNCTION: Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10-methenyltetrahydrofolate to 10-formyltetrahydrofolate (By similarity).
CATALYTIC ACTIVITY: 5,10-methylenetetrahydrofolate + NADP⁺ = 5,10-methenyltetrahydrofolate + NADPH.
CATALYTIC ACTIVITY: 5,10-methenyltetrahydrofolate + H₂O = 10-formyltetrahydrofolate.
PATHWAY: One-carbon metabolism; tetrahydrofolate pathway .
SUBUNIT: Homodimer (By similarity).
SIMILARITY: Belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.
