Properties of an antiserum against Streptomyces hydrogenans 20beta-hydroxysteroid dehydrogenase. 1976

B Lotz, and J Betz, and L Träger

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 27 300 +/- 700.
