Protein
Cytochrome P450 11B1, mitochondrial
Function
Converts 11-deoxycorticosterone to corticosterone and 18-hydroxycorticosterone, and also produces aldosterone. May play a role in the biosynthesis of glucocorticoids as well as mineralocorticoids. 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.
Similarity
Belongs to the cytochrome P450 family.
