In enzymology a methenyltetrahydromethanopterin cyclohydrolase (EC 3.5.4.27) is an enzyme that catalyzes the chemical reaction510-methenyl-5678-tetrahydromethanopterin + H2O 5-formyl-5678-tetrahydromethanopterinThus the two substrates of this enzyme are 510-methenyl-5678-tetrahydromethanopterin and H2O whereas its product is 5-formyl-5678-tetrahydromethanopterin.This enzyme belongs to the family of hydrolases those acting on carbon-nitrogen bonds other than peptide bonds specifically in cyclic amidines.
