Top-scoring residue pair for the SH3 domain. The SH3 domain (orange) and the ligand (green) in the PDB structure 1N5Z are shown. The top-scoring residue pair between Asn71 (red) on the domain and Leu7 of the ligand (blue) is in close physical proximity. Also shown are the MSA residues in the third (Ile73) and fourth (Tyr72) top-scoring pairs.
