 show evidences
Displays cellular triglyceride lipase activity in liver, increases the levels of intracellular fatty acids derived from the hydrolysis of newly formed triglyceride stores and plays a role in very low-density lipoprotein assembly. Displays serine esterase activity in liver. Deacetylates a variety of arylacetamide substrates, including xenobiotic compounds and procarcinogens, converting them to the primary arylamide compounds and increasing their toxicity.

More information is available from:
Can hydrolyze a number of clinical drugs such as flutamide, an antiandrogen drug used for the treatment of prostate cancer; phenacetin, an analgesic antipyretic which has been withdrawn from the market due to its links with renal failure; and rifamycins which have been used as antituberculosis drugs.
