WebIn peptides, steady-state fluorescence can be used to measure the intrinsic fluorescence of Trp, Tyr, and Phe residues, as well as associated dyes, which can change upon exposure to different environmental conditions. This technique can be thus used to detect changes in the conformational states of peptides.

Web20. mar 2001 · The β-Phe residues were inserted at positions 3 and 8, where it was anticipated that interstrand hydrogen bonds would be maintained. The sole difference as compared with conventional all α-amino acid peptide β-hairpins is that the inward- and outward-facing CO and NH groups would not strictly alternate along the strands (Fig. 1). … WebWe have tested this conjecture by probing the effect of Leu, Ile, and Ala mutation of the aromatic Phe residues at positions 19 and 20, on the double-layer hexametric chains of Aβ fragment Aβ₁₆₋₂₂ using explicit solvent all-atom molecular dynamics. As these simulations rely on the accuracy of the utilized force fields, we first ...
