Molecular nature of aldosterone synthase, a member of cytochrome P-450(11 beta) family.
The molecular nature of the aldosterone synthesizing enzymes of cattle and rat is discussed. In bovine adrenal cortex, one molecular species of cytochrome P-450(11 beta) catalyzes aldosterone synthesis as well as 11 beta-hydroxylation. The intactness of the mitochondrial membrane surrounding P-450(11 beta) in the zonae fasciculata-reticularis is essential to keep the aldosterone synthesizing activity of the cytochrome in these zones latent. In rat adrenal cortex, two distinct molecules belonging to a P-450(11 beta) family exist. One is 11 beta-hydroxylase, and the other aldosterone synthase.
