Carboxylesterases that catalyzes the hydrolysis of pyrethroids pesticides. Hydrolyzes permethrin faster than cypermethrin (By similarity). Hydrolyzes retinyl esters (PubMed:12230550). all-trans-retinyl hexadecanoate + H2O = all-trans-retinol + H(+) + hexadecanoate (-)-trans-permethrin + H2O = (1S,3R)-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate + (3-phenoxyphenyl)methanol + H(+) kcat is 0.05 min(-1) with retinyl palmitate as substrate. Expressed in liver, stomach, small intestine and kidney. Belongs to the type-B carboxylesterase/lipase family.
