Levels of the purine nucleoside triphosphates are decreasing towards the end of log phase growth of Streptomyces hydrogenans. Induction of 20beta-hydroxysteroid dehydrogenase by addition of 11beta,21-dihydroxy-4,17(20)-pregnadien-3-one to the growth medium leads to a pronounced drop in purine nucleoside triphosphate levels with is irreversible in contrast to the initial loss and later accumulation of RNA.
在氢化链霉菌对数生长期末期,嘌呤核苷三磷酸的水平在下降。向生长培养基中添加11β,21-二羟基-4,17(20)-孕二烯-3-酮诱导20β-羟基类固醇脱氢酶,会导致嘌呤核苷三磷酸水平显著下降,这与RNA最初的减少及随后的积累不同,是不可逆的。
