Supplementary Figure 1: Plot of all PDB structures analyzed
From: Visualization and analysis of non-covalent contacts using the Protein Contacts Atlas

a, The number of residues (x-axis) vs the number of non-covalent residue contacts (y-axis) in each PDB. b, The number of atoms (x-axis) vs the number of non-covalent atomic contacts (y-axis) in each PDB. Each dot represents a PDB structure. On average, each of these structures contains 5,677 atoms, 45,042 atomic contacts, 684 residues, 3,043 residue contacts, 3 chains, 2,441 atomic contacts between chains, and 125 residue contacts between chains.
