Promoter region of P. aeruginosa cheY2. The transcriptional start sites, which were determined by 5′ RACE and DNA sequencing, are indicated by the angled arrow. Numbering is relative to the transcriptional start site (the A nucleotide). The putative translation start site, ribosome-binding site (RBS), and −35 promoter sequence are underlined. Double underlining indicates a putative RpoS −10 region.
