Abstract
We report a conserved motif upstream genes proA and proB widely represented among y-pro- teobacteria, particularly in the genera Pseudomonas, Marinobacter and Shewanella. The conserved protein-DNA binding sites are 8 bp-long. Some genes have a duplet of sites for cooperative factor binding. The phylogenetic profiles of binding sites and all protein factors were compared. We identify a tetR family protein, an ortholog of the NP_249058 protein from P. aeruginosa PAO1, as a transcription factor. Our algorithm was applied to construct the tree of species with predicted regulation of the pro genes. The phylogeny of pro genes, transcription factors phylogeny and their binding sites phylogeny were mapped onto the tree of species with our algorithm. The obtained scenario displays important HGT and the related events.
