Identification
HMDB Protein ID CDBP00432
Secondary Accession Numbers Not Available
Name Cytochrome P450 11B1, mitochondrial
Description Not Available
Synonyms
  1. CYPXIB1
  2. Cytochrome P-450c11
  3. Cytochrome P450C11
  4. Steroid 11-beta-hydroxylase
Gene Name CYP11B1
Protein Type Metal Binding
Biological Properties
General Function Involved in monooxygenase activity
Specific 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.
