Protein attributes

Sequence length	276 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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.
Catalytic activity	5,10-methylenetetrahydrofolate + NADP(+) = 5,10-methenyltetrahydrofolate + NADPH. 5,10-methenyltetrahydrofolate + H(2)O = 10-formyltetrahydrofolate.
Pathway	One-carbon metabolism; tetrahydrofolate pathway.
Subunit structure	Homodimer By similarity.
Sequence similarities	Belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.
