title: Evidence of an active glucose uptake in Rhizobium meliloti.
abstract: Rhizobium meliloti M5N1 showed immediate uptake of glucose. Glucose accumulation was a saturable function of the glucose concentration, and km and Vmax values for uptake were determined. The glucose uptake system was found to be proteic with a turnover of about 6 h. This system was observed to be an active ATP-dependent process, since it was severely inhibited by uncouplers. Glucose analogues and others hexoses had some inhibitory effects on glucose uptake, but not polyols and lactose.
