In enzymology, a methenyltetrahydrofolate cyclohydrolase (EC 3.5.4.9) is an enzyme that catalyzes the chemical reaction

5,10-methenyltetrahydrofolate + H2O 10-formyltetrahydrofolate

Thus, the two substrates of this enzyme are 5,10-methenyltetrahydrofolate and H2O, whereas its product is 10-formyltetrahydrofolate.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines.

This enzyme participates in glyoxylate and dicarboxylate metabolism and one carbon pool by folate.
