Abstract excerpt
Normally glucosamine (GlcN) is not a substrate for EIICB(Glc) of the glucose phosphotransferase system (PTS), encoded by ptsG, but it is transported by the mannose (Man) PTS, encoded by manXYZ. A mutation, umgC, has been described in Escherichia coli which allows a strain mutated in the Man PTS to grow on GlcN. The umgC mutation was mapped to the ptsG region and was proposed to make ptsG expression constitutive....
