Table 4 The Proportion of Interface Residues in Datasets used in this Study.

From: HomPPI: a class of sequence homology based protein-protein interface prediction methods

  1. a When a chain interacts with more than one other chain, the interfaces are counted separately. For example, for protein complex 2phe C:AB, the interface of C with A and the interface of C with B are regarded as two disordered interfaces.
  2. b Residues that missing from PDB structures are not counted.
  3. c For disordered interface datasets S1 and S2, only disordered interfaces are counted.
