Growth recovery on glucose under aerobic conditions of an Escherichia coli strain carrying a phosphoenolpyruvate:carbohydrate phosphotransferase system deletion by inactivating arcA and overexpressing the genes coding for glucokinase and galactose permease.

Abstract excerpt

In Escherichia coli the phosphotransferase system (PTS) consumes one molecule of phosphoenolpyruvate (PEP) to phosphorylate each molecule of internalized glucose. PEP bioavailability into the aromatic pathway can be increased by inactivating the PTS. However, the lack of the PTS results in decreased glucose transport and growth rates. To overcome such drawbacks in a PTS(-) strain and reconstitute rapid growth on...
