In enzymology, a pentanamidase () is an enzyme that catalyzes the chemical reaction pentanamide + H2O pentanoate + NH3 Thus, the two substrates of this enzyme are pentanamide and H2O, whereas its two products are valerate and NH3. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is pentanamide amidohydrolase. This enzyme is also called valeramidase. References EC 3.5.1 Enzymes of unknown structure
