Proline motifs at the C-terminus. Three C-terminal motifs with proline are mapped, with example structures and global and peak-cluster (*) motif data (Abundance/Overrepresentation/Pvalue). Exemplar width is proportional to motif abundance in the corresponding cluster/geometry, while exemplar colour is proportional to overrepresentation. C’P, which provides rigidity for beta-turns stabilized by C”’MCA- > CCapMCC H-bonds, is second only to C’G in importance at the C-terminus
