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 (By similarity). a carboxylic ester + H2O = a carboxylate + an alcohol + H(+) Homodimer. Constitutively expressed, part of a 5 gene operon with multiple promoters. Not ethanol-stress induced. No visible phenotype. Belongs to the lipase/esterase LIP3/BchO family.
