WebAbstract. The polyproline helix type II (PPII) is a regular protein secondary structure with remarkable features. Many studies have highlighted different crucia Webstructures (1-2): (i) α-helix (or 3.6 13 helix) characterized by intramolecular hydrogen bonds between amino acid residues i and i+4 and (ii) β-sheet composed of extended chains with hydrogen bonds between adjacent chains. A major difference between these two main regular secondary structures is the non-local nature of hydrogen bonds.
