Figure 1From: Mirrors in the PDB: left-handed α-turns guide design with D-amino acidsRamachandran plot of three-residue left-handed turns. Plot of φ versus ψ values for residues at the Ncap (black), N1/C1 (orange) and Ccap (blue) positions. Means and standard deviations of (φ, ψ) (purple) for Ncap, N1/C1 and Ccap are (54 ± 6°, 43 ± 13°), (58 ± 7°, 35 ± 12°) and (66 ± 10°,25 ± 11°) respectively.Back to article page
