Figure 1.

Bacterial genome scanning with the 10 T7-like promoter models. A total of 38 enterobacterial and closely related genomes (Supplementary Table S1) were scanned on both strands with each of the 10 models. The individual information distributions were plotted for each scan by using colored squares (Green, 1 site; blue, 2 sites; purple, 3 sites; red, 4 or more sites). Only genomes that have at least one site above 22 bits by any of the 10 models are listed. The cutoff of 23 bits is marked with a vertical line. In this figure 56 sites appear above 23 bits, however, 13 were picked up by more than one model, so actually there are 43 unique sites.
