General annotation (Comments)Hide

Function	Arylacetamide deacetylation is an important enzyme activity in the metabolic activation of arylamine substrates to ultimate carcinogens. Displays major serine hydrolase activity in liver microsomes. Hydrolyzes also flutamide, which is an antiandrogen drug used for the treatment of prostate cancer that occasionnaly causes severe hepatotoxicity. Displays cellular triglyceride lipase activity in liver. Increases intracellular fatty acids derived from hydrolysis of newly formed triglyceride stores. Ref.6 Ref.7
Catalytic activity	Triacylglycerol + H2O = diacylglycerol + a carboxylate.
Subcellular location	Endoplasmic reticulum membrane; Single-pass type II membrane protein. Microsome membrane; Single-pass type II membrane protein Ref.7.
Tissue specificity	Mainly expressed in liver, small intestine, colon and adrenal gland. Ref.7
Sequence similarities	Belongs to the 'GDXG' lipolytic enzyme family.
Biophysicochemical properties	Kinetic parameters: KM=0.8 mM for flutamide Vmax=1.1 nmol/min/mg enzyme toward flutamide
