In enzymology, an arylalkyl acylamidase () is an enzyme that catalyzes the chemical reaction N-acetylarylalkylamine + H2O arylalkylamine + acetate Thus, the two substrates of this enzyme are N-acetylarylalkylamine and H2O, whereas its two products are arylalkylamine and acetate. 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 N-acetylarylalkylamine amidohydrolase. This enzyme is also called aralkyl acylamidase. References EC 3.5.1 Enzymes of unknown structure
