Promoter consensus motifs of R. etli . The sequence logos of three different sigma factors are shown. A) The logo shows the promoter consensus sequences for RpoH, as obtained from 107 putative promoters regions. B) The logo shows the promoter consensus sequences for RpoE, as obtained from 74 putative promoters regions. C) The logo shows the promoter consensus sequences for SigA, as obtained from 96 putative promoters regions (see Methods). The coloured sequence logos were generated using MEME. The scale of bits in each logo is represented by the height of each letter (nucleotide), showing the positional probability of that nucleotide multiplied by the information of the logo. The −35 box consensus motifs are displayed on the left side of the figure, and the −10 box consensus motifs are displayed on the right side of the figure. The 11 to 23-nt spacer region between the two boxes is not shown.
