Methenyltetrahydrofolate_cyclohydrolase
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.
