Abstract excerpt
Uncoupled enzyme IIGlc of the phosphoenolpyruvate (PEP):glucose phosphotransferase system (PTS) in Salmonella typhimurium is able to catalyze glucose transport in the absence of PEP-dependent phosphorylation. As a result of the ptsG mutation, the apparent Km of the system for glucose transport is increased about 1,000-fold (approximately 18 mM) compared with wild-type PTS-mediated glucose transport. An S....
