The cytochrome b5 is reduced by house fly cytochrome P450 reductase in a reconstituted system at a high rate (5.5 s-1), and it stimulates heptachlor epoxidation when reconstituted with house fly cytochrome P450 reductase, cytochrome P450 6A1, phospholipid, and detergent.

The reconstituted system was effective in the epoxidation of the cyclodiene insecticides aldrin and heptachlor, with turnover rates of 12 and 34 min-1, respectively.

The CYP6A2 protein produced in this system metabolized aldrin and heptachlor to their epoxides and metabolized the insecticide diazinon by desulfuration to diazoxon and by oxidative ester cleavage to 2-isopropyl-4-methyl-6-hydroxypyrimidine.
Metabolism in lysates of cells infected with recombinant baculovirus was greatly enhanced by the addition of purified housefly NADPH cytochrome P450 reductase and cytochrome b5.
