Formation of nanofibrillar aggregates by water-soluble beta-structural oligopeptide, (L-Leu-L-Lys)(8)
The alternating oligopeptide Pyr-(LK)(8) doped by a pyrenyl group at the terminal formed helical tape-like aggregates in an aqueous solution at pH 7. Addition of NaCl induced random coil-to-beta-structure transition to show the excimer peak of pyrenyl groups, although no similar result was observed by the corresponding random oligopeptide Pyr-(L8K8).
