(Figure Presented) Local order goes with random coil: An ensemble of peptide structures is generated with over 90% extended conformation for Ala and Pro. The population-averaged long-range distance from the N-terminal spin-label residue (see picture, red dot) to the C-terminal amide proton of Ala (blue dots) is fully consistent with the results from NMR spin relaxation measurements.
