(A) Distribution of homologous interaction pairs considered for the analysis. (B) Distribution of interaction pairs where neither interaction has a charged residue pair. (C) Distribution of unconserved charged residue pairs. (D) Distribution of conserved charged residue pairs. (E) Distribution of correlated reappearance charged residue pairs. For tables (A) and (B), position (X,Y) in a table corresponds to the number of charged residue pairs of the given type between a pair of residues from an interface formed by a protein from SCOP class X and a protein from SCOP class Y. For tables (C–E), position (X,Y) in a table corresponds to the number of two pairs of residues, each pair from a distinct interface formed by a protein from SCOP class X and a protein from SCOP class Y.
