FIG 6 .

Promoter sequence conservation of conserved TSSs. The sequence conservation level is the fraction of the other seven Shewanella species that keep the same base as S. oneidensis MR-1, for each position of the −50/+10 region of TSSs. The red squares highlight the conservation levels of the conserved sites (C) and the blue triangles are for the variable sites (V), as determined from the major promoter motif identified by MEME. (A) TSSs for annotated genes (gTSS); (B) intergenic TSSs (nTSSs); (C) sense internal TSSs (iTSSs); (D) antisense internal TSSs (aTSSs). For panels C and D, only 4-fold-degenerate codon positions were used. Error bars represent 90% confidence intervals.
