creatinine + H₂O $rightleftharpoons$ creatine

Thus, the two substrates of this enzyme are creatinine and H₂O, whereas its product is creatine.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. The systematic name of this enzyme class is creatinine amidohydrolase. This enzyme is also called creatinine hydrolase. This enzyme participates in arginine and proline metabolism.
