Properties of an antiserum against Streptomyces hydrogenans 20beta-hydroxysteroid dehydrogenase.
Antiserum against crystallized 20beta-hydroxysteroid dehydrogenase from Streptomyces hydrogenans was used for different immunodiffusion and immunoprecipitation tests to quantify the bacterial enzyme in cell-free supernatants of the microorganism. After immunoprecipitation and gel electrophoresis the molecular weight of the subunits of 20beta-hydroxysteroid dehydrogenase was calculated to be 27 ...
متن کاملIsoleucine-15 of rainbow trout carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase is critical for coenzyme (NADPH) binding.
Carbonyl reductase-like 20beta-hydroxysteroid dehydrogenase (CR/20beta-HSD) is an enzyme that converts 17alpha-hydroxyprogesterone to 17alpha, 20beta-dihydroxy-4-pregnen-3-one (the maturation-inducing hormone of salmonid fish). We have previously isolated two types of CR/20beta-HSD cDNAs from ovarian follicle of rainbow trout (Oncorhynchus mykiss). Recombinant proteins produced by expression in...
متن کامل20beta-hydroxysteroid dehydrogenase catalyzes ketone-reduction of acetohexamide, an oral antidiabetic drug, in liver microsomes of adult male rats.
We examined the catalytic properties and physiological function of an enzyme responsible for the ketone-reduction of acetohexamide, an oral antidiabetic drug, in liver microsomes of adult male rats. Progesterone, 17alpha-hydroxyprogesterone, cortisone and cortisol, which have a ketone group at 20-position of C21-steroids, were potent inhibitors for ketone-reduction of acetohexamide in liver mic...
متن کامل-Hydroxysteroid Dehydrogenase in Human Aorta
3 -hydroxysteroid dehydrogenase (3 -HSD) is known to be involved in steroid production and/or metabolism and to be expressed in many tissues including adrenal cortex. Expression of this enzyme has also been elucidated in human cardiovascular system but its details remain largely unknown. Therefore, in this study, we examined the status of 3 -HSD in postmortem human aorta utilizing RT-PCR and im...
متن کاملActivation of Human Liver 3a-Hydroxysteroid Dehydrogenase by Clofibrate Derivatives
The NADP-dependent dehydrogenase activity of a predominant isoenzyme of human liver 3a-hydroxysteroid dehydrogenase was activated by antihyperlipidemic drugs, such as bezafibrate and clinofibrate, and by clofibric acid and fenofibric acid (active metabolites of clofibrate and fenofibrate, respectively). The optimal pH of the activation by the drugs was about 7.5, and the concentrations giving m...
