Abstract
A soybean flour-induced, soluble cytochrome P-450 (P-450soy) was purified 130-fold to homogeneity from Streptomyces griseus. Native cytochrome P-450soy is a single polypeptide, with a molecular weight of 47,500, in association with one ferriprotoporphyrin IX prosthetic group. Oxidized P-450soy exhibited visible absorption maxima at 394, 514, and 646 nm, characteristic of a high-spin cytochrome P-450. The CO-reduced difference spectrum of P-450soy had a Soret maximum at 448 nm. When reconstituted with spinach ferredoxin and spinach ferredoxin:NADP+ oxidoreductase, purified cytochrome P-450soy catalyzed the NADPH-dependent oxidation of the xenobiotic substrates precocene II and 7-ethoxycoumarin. In vitro proteolysis of cytochrome P-450soy generated a stable and catalytically active cytochrome P-450, designated P-450soy delta.
