Sysname
pyrethroid-ester hydrolase
Reaction(IUBMB)
trans-permethrin + H2O = (3-phenoxyphenyl)methanol + (1S,3R)-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate [RN:
R09724 ]
Reaction(KEGG)
Substrate
Product
(3-phenoxyphenyl)methanol [CPD:
C19800 ];
(1S,3R)-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate [CPD:
C19844 ]
Comment
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].
