The FRET efficiencies in donor/acceptor pairs in the two termini of designed fluorescent pentapeptides depend on the flexibility of two arms of triazolyl amino acid scaffolds positioned in the center of the backbones inducing predominant β-sheet con

The concept of a relay FRET event is established in a designed trichromophoric pentapeptide containing an o-,m-aromatic amino acid scaffold in the backbone as a novel β-turn mimetic β-sheet folding nucleator. This system would find application in s
