In enzymology, an acetylputrescine deacetylase () is an enzyme that catalyzes the chemical reaction N-acetylputrescine + H2O acetate + putrescine Thus, the two substrates of this enzyme are N-acetylputrescine and H2O, whereas its two products are acetate and putrescine. 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-acetylputrescine acetylhydrolase. This enzyme participates in urea cycle and metabolism of amino groups. References EC 3.5.1 Enzymes of unknown structure
