Definice

Mitochondriální enzym cytochromu P450, který katalyzuje štěpení postranního řetězce C27 cholesterolu na C21 pregnenolon za přítomnosti molekulárního kyslíku a NADPH-cytochrom c-reduktázy. Tento enzym, kódovaný genem CYP11A1, katalyzuje štěpení mezi C20 a C22, což je počáteční a rychlost limitující krok v biosyntéze různých pohlavních steroidních hormonů a hormonů kůry nadledvin.

A mitochondrial cytochrome P450 enzyme that catalyzes the side-chain cleavage of C27 cholesterol to C21 pregnenolone in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP11A1 gene, catalyzes the breakage between C20 and C22 which is the initial and rate-limiting step in the biosynthesis of various gonadal and adrenal steroid hormones.
