Activity of antiterminator protein BglG regulating the beta-glucoside operon in Escherichia coli is controlled by the phosphoenolpyruvate:carbohydrate phosphotransferase system (PTS) in a dual manner. It requires HPr phosphorylation to be active, whereas phosphorylation by the beta-glucoside-specific transport protein EIIBgl inhibits its activity. BglG and… (More)
