Use of engineered enzymes to identify organophosphate and pyrethroid-related toxicity in toxicity identification evaluations
Engineered variants of a carboxylesterase from Lucilia cuprina (E3) and a phosphotriesterase from Agrobacterium radiobacter (OpdA) with enhanced hydrolytic activities against pyrethroid and organophosphate pesticides were evaluated asatoxicity identification evaluation (TIE) manipulation. Reduction in toxicity in the presence of the enzyme provides an indication that the toxicant is the enzyme's target substrate. Carboxy/esterase E3 variants were evaluated to determine if the enzymes could...[Show more]
