Table. 1. Summary of nitrogen metabolic processes controlled by PTS<sup>Ntr</sup>
Organism Phenotype Regulator Mechanism
Escherichia coli ptsN is required for growth on nitrogenous organic ? Unknown
Salmonella enterica ptsN is required for amino-sugar production in the presence of nitrogen sources EIIANtr EIIANtr represses GlmS activation, which is critical for amino-sugar production
Klebsiella pneumoniae Nitrogen fixation is reinforced in ptsN mutants and inhibited in ptsO mutants EIIANtr Dephosphorylated EIIANtr represses nifL and nifH transcription
Overexpression of ptsN downregulates growth on NH4+ EIIANtr EIIANtr represses glnA transcription
Pseudomonas aeruginosa ptsN mutants are unable to utilize nitrogenous organic ? Unknown
Azotobacter vinelandii Nitrogenase activity is repressed in ptsP mutants ? Unknown
Rhizobium etli Transcription of nifH and melanin production are repressed in ptsN and ptsA mutants ? Unknown
