The <scene name='82/829362/Default_scene/4'>alpha-synuclein (1-121)</scene> is about 14 kDa fibril constituted by two protofilaments of 121 residues <ref>DOI 10.7554/eLife.36402</ref>. The presence of many ꞵ-sheet induce a Greek-key motif of 99 Å diameter <ref>DOI 10.1038/s41467-018-05971-2</ref>. Indeed, There are 8 <scene name='82/829362/~~Beta~~-strands/6'>Beta-strands interrupted by glycines</scene>, between the residues 42 to about 102 <ref>DOI 10.7554/eLife.36402</ref>. These glycines help the folding of the molecule by their small size.
