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