The structures are based on a total of 70 restraints, 60 are NOE-derived distance constraints and 10 dihedral angle restraints. The pairwise RMSD for residues 3-12 was 0.38 +/- 0.21 A for the backbone and 1.36 +/- 0.35 A for all heavy atoms. The estimated beta-hairpin population of this peptide is 66 +/- 4%. The first and last two residues (RG) are disordered, because they were added just to avoid aggregation. The side chains of Trp4, Tyr6, Ile9 and Tyr11 are interacting in one side of the beta hairpin, forming a hydrophobic cluster. Asn7 at position L1 of the beta-turn is directed outwards from the beta-hairpin, as expected for a type I' beta-turn.
