Nucleotide sequence of the rpoN gene and characterization of two downstream open reading frames in Pseudomonas aeruginosa

The nucleotide sequence of Pseudomonas aeruginosaa rpoN gene and two neighboring short polypeptides are determined. The amino acid sequences show homology to the rpoN genes of other bacteria in their product sequence and genetic organization. The 3' region of P. aeruginosa rpoN gene contains two additional ORFs encoding short proteins and mutations, causing enhancement of P. aeruginosa generation time.
