Polar pairs at (N’, N4). Examples of polar pair motifs at the positions (N’, N4) are shown, with example structures and global and peak-cluster (*) motif data (Abundance/Overrepresentation/Pvalue). Exemplar widths are proportional to motif abundance in the corresponding cluster/geometry, while exemplar colour is proportional to overrepresentation. These motifs correspond to electrostatic interactions and salt bridges
