The Phosphotransferase System Formed by PtsP, PtsO, and PtsN Proteins Controls Production of Polyhydroxyalkanoates in Pseudomonas putida

Abstract
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 I Ntr (EI Ntr ; encoded by ptsP ), NPr ( ptsO ), and EII Ntr ( ptsN ) act in concert to control the intracellular accumulation of polyhydroxyalkanoates, a typical product of carbon overflow.
