Involved in the detoxification of xenobiotics. Shows maximal activity with C6 substrates, with gradually decreasing activity from C8 to C12 substrates. No activity for higher chain length substrates acids rather than long-chain ones. a carboxylic ester + H2O = a carboxylate + an alcohol + H(+) Optimum pH is 9. Optimum temperature is 70 degrees Celsius. Homodimer. Belongs to the lipase/esterase LIP3/BchO family.
