CC       whereas 3-[(3-cholamidopropyl)dimethylammonio]propane-1-sulfonate
CC       (CHAPS) and octyl alpha-D-glucopyranoside decrease the N-(long-chain-
CC       acyl)ethanolamine deacylase activity (PubMed:22860206). Polysorbate 20
CC       (Tween 20) is inhibitory (PubMed:11463796). Stimulated by endogenous
CC       phospholipids such as choline- or ethanolamine-containing
CC       phospholipids, and dihydrolipoic acid (PubMed:22860206).

CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Kinetic parameters:
CC         KM=35 uM for N-palmitoylethanolamine {ECO:0000269|PubMed:11463796};
CC       pH dependence:
CC         Optimum pH is 5 with N-palmitoylethanolamine as substrate.
CC         {ECO:0000269|PubMed:11463796};
CC   -!- PATHWAY: Lipid metabolism; fatty acid metabolism.
CC       {ECO:0000269|PubMed:11463796, ECO:0000269|PubMed:15655246}.
CC   -!- SUBUNIT: Heterodimer of an alpha and a beta subunit, produced by
CC       autocatalytic cleavage. {ECO:0000250|UniProtKB:Q02083}.
CC   -!- SUBCELLULAR LOCATION: Lysosome {ECO:0000250|UniProtKB:Q02083}. Membrane
CC       {ECO:0000250|UniProtKB:Q02083}; Peripheral membrane protein
CC       {ECO:0000250|UniProtKB:Q02083}.
CC   -!- TISSUE SPECIFICITY: Expressed in brain, cecum, colon, heart, ileum,
CC       kidney, liver, lung, spleen, stomach, submaxillary gland, testis and
CC       thymus. {ECO:0000269|PubMed:15655246, ECO:0000269|PubMed:22860206}.
CC   -!- PTM: N-glycosylated. Tunicamycin treatment causes a reduction in
CC       specific activity against N-palmitoylethanolamine.
CC       {ECO:0000250|UniProtKB:Q02083}.
CC   -!- PTM: Autoproteolytic cleavage at pH 4.5 gives rise to the alpha and
CC       beta subunit. Cleavage gives rise to a conformation change that
CC       activates the enzyme. The same catalytic Cys residue mediates the
CC       autoproteolytic cleavage and subsequent hydrolysis of lipid substrates.
CC       {ECO:0000250|UniProtKB:Q02083}.
CC   -!- SIMILARITY: Belongs to the acid ceramidase family. {ECO:0000305}.
