EC 3.5.1.60     
Accepted name: N-(long-chain-acyl)ethanolamine deacylase
Reaction: N-(long-chain-acyl)ethanolamine + H2O = a long-chain carboxylate + ethanolamine
Other name(s): NAAA (gene name); N-acylethanolamine amidohydrolase; acylethanolamine amidase
Systematic name: N-(long-chain-acyl)ethanolamine amidohydrolase
Comments: This lysosomal enzyme acts best on palmitoyl ethanolamide, with lower activity on other N-(long-chain-acyl)ethanolamines. It is only active at acidic pH. Unlike EC 3.5.1.99, fatty acid amide hydrolase, it does not act on primary amides such as oleamide, and has only a marginal activity with anandamide. The enzyme is translated as an inactive proenzyme, followed by autocatalytic cleavage into two subunits that reassociate to form an active heterodimeric complex.
