Comments
  • FUNCTION: Converts 11-deoxycorticosterone into corticosterone, 18-hydroxycorticosterone, and aldosterone. Also can catalyze the conversion of 11-deoxycortisol to cortisol, 18-hydroxycortisol and cortisone.
  • CATALYTIC ACTIVITY: A steroid + reduced adrenal ferredoxin + O2 = an 11-beta-hydroxysteroid + oxidized adrenal ferredoxin + H2O.
  • CATALYTIC ACTIVITY: Corticosterone + reduced adrenal ferredoxin + O2 = 18-hydroxycorticosterone + oxidized adrenal ferredoxin + H2O.
  • COFACTOR: Heme group (By similarity).
  • SUBCELLULAR LOCATION: Mitochondrion membrane.
  • TISSUE SPECIFICITY: Adrenal cortex.
  • INDUCTION: A 12-fold increase was seen in the presence of a low sodium-high potassium diet.
  • SIMILARITY: Belongs to the cytochrome P450 family.
