Fig. 1. The nitrogen-PTS of E. coli (modified from Jahn et al., 2013). The nitrogen-phosphate transport system consists of EINtr (ptsP), NPr (ptsO), and EIIANtr (ptsN). The ptsN and ptsO genes are found in the same operon with the rpoN gene encoding σ54. PTSNtr regulates various physiological activities of cells through a series of phosphorylation cascade systems in the direction of PEP → EINtr → NPr → EIIANtr.
