Abstract excerpt
9 alpha-Hydroxylation of 4-androstene-3,17-dione (AD) and 1,4-androstadiene-3,17-dione (ADD) is catalysed by 3-ketosteroid 9 alpha-hydroxylase (KSH), a key enzyme in microbial steroid catabolism. Very limited knowledge is presently available on the KSH enzyme. Here, we report for the first time the identification and molecular characterization of genes encoding KSH activity. The kshA and kshB genes, encoding KSH...
