A number of short peptides and larger proteins are able to self‐assemble to form cross‐β amyloid‐like fibrils.1 These β‐sheet peptides have been increasingly explored as potentially useful bionanomaterials due to their propensity to spontaneously assemble to form large complex structures from simple monomers.2 An eight‐residue fragment of the amyloidogenic Parkinson’s disease related peptide α‐synuclein,3 named αSβ1, assembles to form a helical nanostructure. This evidence concerns the gene ASB1 and Parkinson disease.
