FMO1 also metabolized the commonly used insecticide fenthion to its (+)-sulfoxide, with relatively high catalytic efficiency.

Earlier reports have demonstrated that recombinant flavin-containing monooxygenase 1 (FMO1) catalyzes the oxidation of the organophosphate pesticide fenthion to (+)-fenthion sulfoxide in a stereoselective fashion.

The relative contribution of FMO1 and FMO3 to the sulfoxidation of carbophenothion, demeton-O, ethiofencarb, fonofos, and methiocarb also was investigated by using baculovirus-expressed recombinant proteins.
Stereoselective sulfoxidation of fenthion and methiocarb by human liver, kidney, and microsomes was investigated.

Several cytochrome P450 isoforms and flavin-containing monooxygenase 1 exhibited these oxidase activities.
