The DNA sequence downstream of the Pseudomonas putida rpoN gene and the adjacent ORF102 was determined. This region encodes an ORF (ORF154) whose gene product was found to be homologous to a family of phosphotransferases. Insertional mutagenesis and analysis of mRNA transcripts showed that the rpoN gene is transcribed separately from the two downstream genes. The rpoN promoter was localized to an 86 nucleotide-long region upstream of the rpoN gene by examination of the expression of a series of rpoN::lacZ fusions. The expression of rpoN in P. putida was independent of the nitrogen status of the cell but was 5 times higher in the rpoN mutant than in the wild-type strain, suggesting that the expression of the rpoN gene in this organism is autoregulated.
