Steroid initiated enzyme induction (Δ5-Ketosteroid-Isomerase, 3α-Hydroxysteroid-Dehydrogenase, and 3β.17β-Hydroxysteroid-Dehydrogenase) in Pseudomonas testosteroni was investigated with respect to the kinetics of induction, operon control of the induced enzymes, and the relative strengths of various inducers. The induction process was followed indirectly by selective inhibition of different stages in the protein synthetic pathway. Comparisons between bacterial and mammalian steroid induction are discussed.
