REGULATION OF CARBOHYDRATE TRANSPORT-SYSTEMS IN RHODOCOCCUS-MINIMUS AT THE LEVEL OF PROTEIN-SYNTHESIS

Glucose transport and its regulation has been studied in Rhodococcus m inimus B293. It was shown that in this Rhodococcus, depending on the g lucose concentration in the medium, there are two glucose-transport sy stems. Under oligotrophic conditions the inducible galactose transport system S1 is activated; in the presence of excess substrate, the cons titutive transport system S2 is implemented. The Sl system is inhibite d by glucose. The negative glucose effect is manifested both at the le vel of protein synthesis and at the level of regulation of transport-s ystem activity by activation and inactivation of its proteins.
