Abstract

Immunoprecipitation of polyribosomes from Streptomyces hydrogenans synthesizing 20beta-hydroxysteroid dehydrogenase was performed by immunoelectrophoresis. Only polyribosomes from cells induced by 11beta, 21-dihydroxy-4, 11(20)-pregnadien-3-one in vivo were precipitated by immunoglobulins specific for 20beta-hydroxysteroid dehydrogenase. No unspecific precipitations with polysomes from control cells cultivated in the absence of steroids were observed. Therefore, 11beta, 21-dihydroxy-4, 17(20)-pregnadien-3-one increases the number of biological active polyribosomes involved in 20beta-hydroxysteroid dehydrogenase synthesis, presumably by specific stimulation of mRNA synthesis in Streptomyces hydrogenans.
