Exploring the Composition of Protein-Ligand Binding Sites on a Large Scale
Figure 4
Frequencies of BB-only contacts in binding sites, sorted by increasing frequency on the protein surface.
Surface residues with 5 Å2 or greater backbone SASA are shown. Gly interactions are shown as BB-only to stress that it constitutes the vast majority of such contacts. Due to rounding, rows may occasionally sum to a value other than 100%.
