CYP11B1 [ENSP00000292427]
cytochrome P450, family 11, subfamily B, polypeptide 1; Has steroid 11-beta-hydroxylase activity. In addition to this activity, the 18 or 19-hydroxylation of steroids and the aromatization of androstendione to estrone have also been ascribed to cytochrome P450 XIB
CYP19A1 [ENSP00000260433]
cytochrome P450, family 19, subfamily A, polypeptide 1; Catalyzes the formation of aromatic C18 estrogens from C19 androgens
