Abstract

The nucleotide sequence of Pseudomonas aeruginosa phoB was determined. The sequence data suggest that the PhoB polypeptide consists of 229 amino acid residues and has a predicted molecular weight of 25,708. In the regulatory region of the gene, a very well conserved phosphate box was found. The sequence data also predicted the presence of an open reading frame downstream of phoB, which could be phoR. The deduced amino acid sequence of phoB was significantly homologous to that of the Escherichia coli phoB gene product and to those of several known procaryotic transcriptional regulators such as PhoP, OmpR, VirG, Dye, NtrC, and AlgR.
