C(X) is a Pearson product–moment correlation between the amino acid scale described in column and the published amino acid scale X. When X is HoD (homodimer), the amino acid scale is from Bahadur et al. (18); when X is HeD (Heterodimer) or Pcore (protein core), the amino acid scales are from Albou et al. (27); when X is Crystal (crystal packing), it is from Bahadur et al. (15). HoD,X (such as HoD,HeD) indicates an homodimer/X polyvalent binding site.
