FIG. 3.

DNase I footprints of partially purified Mcm1 binding to ECB-containing regions of the CDC6, CDC47, and SWI4 promoters. (A) DNase I footprints were performed as described for Fig. 2 using strand-specific probes from the CDC6, CDC47, and SWI4 promoters. (B) Summary of the DNase I footprints. The 16-bp palindromes of each ECB are indicated with gray boxes. The positions of protected sequences (black lines) and DNase I-hypersensitive sites (black dots) are indicated in the promoter sequences.
