ABSTRACT
We compare the changes in side chain conformations that accompany the formation of protein-protein complexes, in residues forming either the interface or the remainder of the solvent-accessible surface of the proteins in the Docking Benchmark 3.0. We find that the interface residues undergo significantly more changes than other surface residues, and these changes are more likely to convert them from a high-energy torsion angle state to a lower-energy one than the reverse. Moreover, in both the unbound proteins and the complexes, the interface residues are more frequently found to be in a high-energy torsion angle state than the noninterface residues. As these differences exist before the binding step, they may be relevant to specificity and help in identifying binding sites for docking predictions.
