Protein

Cytochrome P450 11B1, mitochondrial

Gene

CYP11B1

Organism
Mesocricetus auratus (Golden hamster)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Forms corticosterone from 11-deoxycorticosterone. Possesses high and nearly equal 11-beta-hydroxylase and 19-hydroxylase activities and a lower 18-hydroxylase activity. Involved in the formation of the precursor of 19-nor-deoxycorticosterone, a very potent mineralocorticoid involved in the development of essential hypertension.

Catalytic activityi

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