Abstract
The intracellular localization of an enzyme system which alters the 17,21-dihydroxy-20-ketone side-chain of cortisone was studied in rat liver. The nuclei and mitochondria were inactive. The enzyme was approximately equally distributed between a microsome fraction sedimented at 20,000 x gravity and the supernatant fraction. The enzyme activity was greatly enhanced on addition of Mg and either glucoses-phosphate, citrate, or isocitrate.Keywords
