Electrophoresis of Drosophila microsomes resolves two major heme-containing protein bands with apparent molecular weights of 59,290 (band a) and 55,750 (band b). The hemoproteins in these two bands can account for most of the cytochrome P-450 in the organism. Band a is present in all strains examined: band b is not. Dimethylnitrosamine demethylase, a P-450 enzyme, is a component of band b.
