CYP11B2 [ENSP00000325822]
cytochrome P450, family 11, subfamily B, polypeptide 2; Preferentially catalyzes the conversion of 11- deoxycorticosterone to aldosterone via corticosterone and 18- hydroxycorticosterone
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
