	Abstract

The genome of Pseudomonas putida KT2440 encodes five proteins of the phosphoenolpyruvate-carbohydrate phosphotransferase system (PTS). Two of these (FruA and FruB) form a dedicated system for fructose intake, while EI^Ntr (encoded by ptsP), NPr (ptsO) and EII^Ntr (ptsN) act in concert to control the intracellular accumulation of polyhydroxyalkanoates (PHAs), a typical product of carbon overflow.
