Figure 2.

Ribbon plot of the complex of α-BTX with the library-derived peptide. α-BTX residues are shown in grey (for β-sheet regions) and in green. Peptide backbone is shown in pink; side chains of peptide residues interacting with the toxin (Y3^P, Y4^P, E5^P, L8^P) as well as of Y11^P which forms the hydrophobic core of the peptide, are shown in yellow. The figure was generated using the program molmol (35).
