<jats:title>Abstract</jats:title> <jats:p>Designed two peptides, Ac-Trp-Lys-Ala13-Lys-NH2 and Ac-Trp-Lys-Ala15-Lys-NH2 were synthesized by utilizing natural L-amino acids and were capable of performing a structural transition from β-sheet to α-helix. The α–β transition of the designed peptides was induced by interstrand hydrophobic interaction. This shows that our designed peptides may be an model system for the elucidation of misfolding and transformation mechanism of pathogenic proteins.</jats:p>
