Tandem T7-like promoters in S.flexneri genomes. A total of 12 T7-like promoters that appear in tandem are identified in the genomes of S.flexneri strain 2457T (A) and strain 301 (B), and the sequence walkers (21) are shown. Different colored rectangles indicate different promoters (by hue) and their strengths (by saturation). Each cluster corresponds to one island and the island names are given in the lower right corner of each box. A double slash means that an intervening sequence is not shown; the size (in bp) is given in parenthesis. A black triangle in B-2 indicates the insertion point of IS911.
