Figure 5. — Footprinting of C.Esp1396I complexes with esp1396I promoters. A 4-fold (lane 2) or 8-fold (lane 3) excess of C.Esp1396I was combined with Pesp1396ICR (A) or Pesp1396IM (B) end-labeled DNA fragments; complexes were allowed to form and were footprinted with DNase I. On the left of each panel, the sequences of each promoter are shown along with promoter elements (red) and symmetry-related features of C.Esp1396I binding sites. In (B), only imperfect tetranucleotide repeats from a predicted second set of inverted repeats (see Figure 1) are shown at the top of the figure.
