Reaction: trans-permethrin + H2O = (3-phenoxyphenyl)methanol + (1S,3R)-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate
Other name(s): pyrethroid-hydrolyzing carboxylesterase; pyrethroid-hydrolysing esterase; pyrethroid-hydrolyzing esterase; pyrethroid-selective esterase; pyrethroid-cleaving enzyme; permethrinase; PytH; EstP
Systematic name: pyrethroid-ester hydrolase
Comments: The enzyme is involved in degradation of pyrethroid pesticides. The enzymes from Sphingobium sp., Klebsiella sp. and Aspergillus niger hydrolyse cis-permethrin at approximately equal rate to trans-permethrin [1-3]. The enzyme from mouse hydrolyses trans-permethrin at a rate about 22-fold higher than cis-permethrin [4].
