Disulphide bond conservation plotted against sequence identity for all the pairwise comparisons among the members of disulphide bond containing SCOP structural families. A total of 34,752 pairwise comparisons are made between members of the 300 families analysed. A two-dimensional scatter plot is also illustrated in the inset.
