title: Regulation by testosterone of the glucosamine-6-phosphate synthase activity in the male reproductive organs of rat.
abstract: Accessory reproductive organs of male rat were found to contain high activities of glucosamine-6-phosphate synthase (glucosaminephosphate isomerase (glutamine-forming), EC 5.3.1.19). Castration caused drastic reduction (75%) in the enzyme activity of ventral prostate. Testosterone propionate administration restored the enzyme activity while cortisol and estradiol-17 beta did not cause any effect. Cycloheximide blocked the stimulation caused by testosterone.
