General annotation (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. HAMAP-Rule MF_01576
Catalytic activity	5,10-methylenetetrahydrofolate + NADP+ = 5,10-methenyltetrahydrofolate + NADPH. HAMAP-Rule MF_01576 5,10-methenyltetrahydrofolate + H2O = 10-formyltetrahydrofolate. HAMAP-Rule MF_01576
Pathway	One-carbon metabolism; tetrahydrofolate interconversion. HAMAP-Rule MF_01576
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.
