cytochrome P-450 17alpha-hydroxylase-17,20-lyase, CYP17, is a multifunctional enzyme. CYP17 catalyzes at the same active site not only the hydroxylation process but also an acyl-carbon bond cleavage reaction which involves the nucleophilic attack of the ferric-peroxyanion, Fe(III)-O-O-, on the acyl-carbon to furnish a tetrahedral intermediate which fragments, leading to acyl-carbon cleavage
-

?

-
-
for the formation of the 16,17-ene steroid, the Fe(III)-O-O- species is trapped by the progestogen, prior to hydroxylation, and the resulting peroxy adduct decomposes to generate a C-17 radical, which is neutralized by a disproportionation reaction involving the loss of C-16-hydrogen atom, mechanism of the acyl-carbon bond cleavage reactions catalysed by CYP17, pathways for the formation of three cleavage products from peroxy adducts, overview

CYP21
direct molecular interactions, with electrostatic interactions playing a crucial role, between steroidogenic enzymes CYP17 and CYP21, EC 1.14.99.10, that are localized in endoplasmic reticulum membranes of adrenal cortex and involved in biosynthesis of corticosteroid hormones. The interaction in vitro reduces the catalytic activities of both enzymes at high ionic strength, i.e. 300 mM NaCl, while it increases activity at low ionic strength, i.e. 100 mM NaCl, overview
