Top-scoring residue pair for the natural PDZ domain. The PDZ domain (orange) and the ligand (green) in the biological assembly (dimer) of the PDB structure 2H2C are shown. The top-scoring residue pair between Leu60 (red) on the domain and position -1 of the binding motif on the ligand (blue) are in physical contact.
