Glycine motifs at the C-terminus. Three C-terminal motifs with glycine are shown, 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’G is the most important of all C-terminal motifs, because it enables Schellman loops with its left-handed alpha conformation
