In enzymology, a carnitinamidase () is an enzyme that catalyzes the chemical reaction L-carnitinamide + H2O L-carnitine + NH3 Thus, the two substrates of this enzyme are L-carnitinamide and H2O, whereas its two products are L-carnitine 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 L-carnitinamide amidohydrolase. Other names in common use include L-carnitinamidase, carnitine amidase, and L-carnitine amidase.
