Protein

Cytochrome P450 11B1, mitochondrial

Gene
CYP11B1
Organism
Ovis aries (Sheep)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

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 activityi

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

Cofactori

Heme group By similarity.
