Figure 5.

Analysis with secondary structure and regular secondary structure (β-sheet and helix) composition on residue base. (a) Average ratio of each secondary structure (including helix, β-sheet, coil, and turn) for all residues and (b) β-sheet ratio as a function of amino acid residue. Illustrations of the β-strand arrangements of (c) the CD44s stem region, cluster 1; (d) the CD44s stem region, cluster 2; and (e) the CD44v6 stem region, cluster 1. (f) Helix ratio as a function of amino acid residue.
