Amidase with broad substrate specificity, catalyzing the hydrolysis of a wide range of N-substituted amides, and, to a lesser extent, the hydrolysis of non-substituted amides. Acid para-nitroanilides (4'-nitroacetanilide, Gly-pNA, Ala-pNA, Leu-pNA) are the best substrates for this enzyme. N-substituted acrylamides (isopropyl acrylamide, N,N-dimethyl-aminopropyl acrylamide, and methylene-bis-acrylamide), N-acetyl derivatives of glycine, alanine and leucine, and aliphatic amides (acetamide, acrylamide, isobutyramide, n-butyramide, and valeramide) can also be used as substrates but with less efficiency.
