    • For consistency, all peptides were labeled with DBO at the C-terminus. A control experiment with the turn-derived peptide DBO-TLTGKY, where the terminal positions of probe and quencher are exchanged but where the peptide backbone remains the same, yielded the same quenching rate constant within error as the YTLTGK-DBO peptide (Table 2), which supports the idea that the measured quenching rates reflect an intrinsic dynamic property of the peptide backbone, namely its flexibility.

    • diff = 8RT/3η), this sequential treatment allows one to explicitly consider the fact that the attachment of a peptide chain to a probe or quencher will necessarily reduce its diffusion coefficient but not enhance the reaction rate, since the true reaction radius remains confined to the volume around the reactive sites of the probe and quencher itself.

    • The collision radius (a) of 4 Å corresponds approximately to the sum of the van der Waals radii of probe (DBO) and quencher (Trp/Tyr) and is the average distance of van der Waals complexes produced by molecular dynamics simulations (M. Zacharias, D. Roccatano, unpublished results). In addition, the distance between the reactive atoms in the transition states for quenching (see Scheme 3) lies within this range.
