Abstract

The major mineralocorticoid hormone aldosterone is secreted from the zona glomerulosa of the adrenal cortex. Aldosterone is synthesized from cholesterol via a series of hydroxylations and oxidations. The enzymes involved in these reactions are mostly members of the cytochrome P450 superfamily. The final steps of this pathway, the conversion of 11-deoxycorticosterone (DOC) to aldosterone, require conversion via the intermediates 18-hydroxy-DOC or corticosterone and 18-hydroxycorticosterone. There are significant differences between species in the number of genes that encode the P450(11beta)-related enzymes (CYP11B) involved in these steps and the zonal distribution of their expression. One en..
