TABLE 7.

Peptide-side attention analysis. Structural property comparisons between the large- and small-attention residue groups are shown.

^a Mean and standard deviation (for the 39 structures) of the proportion of residues that satisfy the property shown in the first column.

^b Three residues from the beginning and three from the end of the peptide.

^c In the last two properties, per-residue averages were used instead.
