General annotation (Comments)

Function

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.

Catalytic activity

A steroid + reduced adrenal ferredoxin + O2 = an 11-beta-hydroxysteroid + oxidized adrenal ferredoxin + H2O.

Cofactor

Heme group By similarity.

Subcellular location

Mitochondrion membrane.

Sequence similarities

Belongs to the cytochrome P450 family.
