Groups of rats dosed i.p. daily for 1 or 2 weeks with 40 or 200 mg/kg malathion showed an increase in epoxide hydrolase activity (1 week, 200 mg/kg) and glutathione S-transferase activity (1 week, 200 mg/kg; 2 weeks 40 and 200 mg/kg).

Similarly, the difference due to the strain and the H-2 locus was detected in the activities of P-450-independent enzymes such as malathion and diethyl succinate carboxylesterases, glutathione S-transferase, and epoxide hydrolases in microsomal and cytosolic fractions.

The hydrolytic enzymes involved in insecticide metabolism are the phosphorotriester hydrolases, carboxylesterases, carboxylamidases and epoxide hydrolases.
Carboxylesterases hydrolyze the carboethoxy group of malathion and also have hydrolytic activity toward certain synthetic pyrethroids.
