In enzymology, an aculeacin-A deacylase () is an enzyme that catalyzes the chemical reaction that cleaves the amide bond in aculeacin A and related neutral lipopeptide antibiotics, releasing the long-chain fatty acid side chain. This enzyme belongs to the family of hydrolases, specifically those acting on carbon-nitrogen bonds other than peptide bonds in linear amides. The systematic name of this enzyme class is aculeacin-A amidohydrolase. This enzyme is also called aculeacin A acylase. References EC 3.5.1 Enzymes of unknown structure
