Definice

Mikrozomální cytochrom P450, který katalyzuje 17-alfa-hydroxylaci progesteronu nebo pregnenolonu a následné odštěpení zbývajících dvou uhlíků na C17 za přítomnosti molekulárního kyslíku a NADPH-cytochrom c-reduktázy. Tento enzym, kódovaný genem CYP17, vytváří prekurzory pro syntézu glukokortikoidů, androgenů a estrogenů. Defekty v genu CYP17 způsobují vrozenou hyperplazii nadledvin a abnormální sexuální diferenciaci.

A microsomal cytochrome P450 enzyme that catalyzes the 17-alpha-hydroxylation of progesterone or pregnenolone and subsequent cleavage of the residual two carbons at C17 in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP17 gene, generates precursors for glucocorticoid, androgen, and estrogen synthesis. Defects in CYP17 gene cause congenital adrenal hyperplasia (ADRENAL HYPERPLASIA, CONGENITAL) and abnormal sexual differentiation.
