  1. § Already mutated hubs have been excluded from this table.
  2. 1 The underlined monomers are the ones where some mutations have already been carried out.
  3. 2 No hubs are obtained at Imin = 4% in 1CBW. Hence, hubs at Imin = 2% are used for prediction.
  4. 3 1DAN and 3HHR are proteins where a large number of mutations (>100) have been carried out, which have ΔΔG < 1 kcal/mol. These mutations have not been included in this analysis.
  5. 4 ** All hubs identified at Imin = 4% have already been mutated.
  6. 5 h or l accompanying a residue name corresponds to the heavy and the light chains of the corresponding antibodies.
