EC                 Enzyme                                 

N-(long-chain-acyl)ethanolamine deacylase;
NAAA (gene name);
N-acylethanolamine amidohydrolase;
acylethanolamine amidase
Acting on carbon-nitrogen bonds, other than peptide bonds;
In linear amides
N-(long-chain-acyl)ethanolamine amidohydrolase
N-(long-chain-acyl)ethanolamine + H2O = a long-chain carboxylate + ethanolamine [RN:R02041]
N-(long-chain-acyl)ethanolamine [CPD:C04080];
H2O [CPD:C00001]
long-chain carboxylate [CPD:C00347];
ethanolamine [CPD:C00189]
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, 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.
