 One of the outliers,immunoglobulin (1LMK). A total of 39 residues out of 238 are identified as HFF residues, which clustered into four groups. The surface patches identified from the HFF residues are composed of 26 residues clustered into six patches. In A and B, the original and a second binding sites are displayed, respectively. The interface residues are colored yellow, the surface patches are colored red, and the intersection residues are colored orange.
