Figure 6
Scatter plot of the enrichment score ΔEenr(a, b) vs normal contact potential Enorm(a, b). Each point is for an amino acid pair (a, b) and is colored according to amino acid types: black for pairs of aromatic residues (HIS, PHE, TRP, TYR); magenta for CYS-CYS; green for the rest. The dashed line is a linear fit with slope −0.12. Error bars are computed with a boostrapping procedure and we plot only errors for ΔEenr as those for Enorm are smaller than the symbol size.
