[The effect of glucose on induced synthesis of exocellular protease of Serratia marcescens].
The sensitivity of induced synthesis of exocellular protease to catabolyte repression was studied in Serratia marcescens growing on media containing inductors, viz. leucine and albumin. A lower sensitivity of the leucine-induced synthesis of the enzyme to glucose as compared to that induced by albumin seems to be caused by the penetration of leucine into the cell prior to the appearance in the medium of organic acids, possible inhibitors of its transport, whereas on the medium containing albumin, leucine appears only after hydrolysis of the protein by the "basal" enzyme.
