Figure 1
The three independent molecules of LGS (A, B and C). Dotted lines show intramolecular hydrogen bonds. H atoms have been omitted for clarity. Residue names and heteroatoms are labelled on molecules A and B. The phenyl rings of D-Phe protrude along the long axis of the peptide molecule, except for D-Phe9C. No intermolecular hydrogen bond is formed between atoms N11C and O82C, and the turn structure of D-Phe9–Pro10 in molecule C is not classed as any β-turn type. The side chains of Leu8B and Leu2C are disordered. Displacement ellipsoids are drawn at the 50% probability level. Side views are shown in Fig. S4 in the supporting information. |
