FIG. 6.

Sliding amino acid window. A window of 10 contiguous BLIP residues was scanned across the BLIP sequence starting at position 1. Each set of 10 contiguous residues was scored for the number of residues that make contact with the TEM-1 β-lactamase on the basis of the cocrystal structure of TEM-1 β-lactamase and BLIP (44). The positions of BLIP amino acid residues that come into contact with the TEM-1 β-lactamase were obtained from the X-ray structure of the BLIP-TEM-1 β-lactamase complex (44). An arrow indicates the 10-residue window representing the BP41-50 peptide. The starting residue for every 10th window is indicated below the graph.
