Figure 4.
(a) Peptides 8 and 9. (b) Overlay of the 10 best structures for 9 in aqueous buffer obtained via NOE-restrained dynamics (see text for details). RMSD for the backbone atoms in the strand segments is 0.320 + 0.117 Å. (c) ΔδCαH = δCαH(observed) − δCαH(random coil), or CSD, for α-amino acid residues of macrocycle 9 dissolved in aqueous buffer or in a 1:1 vol:vol solution of aqueous buffer and 2,2,2-trifluoroethanol (TFE).
