Figure 4 Summary of contacts of PHO4 residues with DNA bases and phosphate groups. Schematic summary of the base and phosphate contacts made by each monomer. The DNA is represented as a cylindrical projection with phosphates indicated by circles. The E-box bases are stippled and recognized flanking bases are hatched. Base pair recognitions are indicated by bold-lined arrows, and phosphate recognitions by thin-lined arrows. The weak interaction is shown by dashed-lined arrows. All contacts are via side chains.
