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. simulated annealing combined with torsion angle dynamics (DYANA) 6 lower rmsd with respect to mean 1 mM Peptide MBH12 90% H2O/10% D2O 1 mM Peptide MBH12 100% D2O 1 mM Peptide MBH12 40% CD3OD, 60% H2O Bruker collection XwinNMR 2.6 Bruker data analysis XwinNMR 2.6 Guntert, P. et al. structure solution DYANA 1.5 van Gunsteren refinement GROMOS 96 500 Bruker DRX ARG 1 n 1 ARG 1 A GLY 2 n 2 GLY 2 A LYS 3 n 3 LYS 3 A TRP 4 n 4 TRP 4 A THR 5 n 5 THR 5 A TYR 6 n 6 TYR 6 A ASN 7 n 7 ASN 7 A GLY 8 n 8 GLY 8 A ILE 9 n 9 ILE 9 A THR 10 n 10 THR 10 A TYR 11 n 11 TYR 11 A GLU 12 n 12 GLU 12 A GLY 13 n 13 GLY 13 A ARG 14 n 14 ARG 14 A author_defined_assembly 1 monomeric 1.0000000000 0.0000000000 0.0000000000 0.0000000000 1.0000000000 0.0000000000 0.0000000000 0.0000000000 1.0000000000 1_555 x,y,z identity operation 0.0000000000 0.0000000000 0.0000000000 A N TRP 4 A N TRP 4 A O TYR 11 A O TYR 11 2 A A H O TRP TYR 4 11 1.57 3 A A H O TRP TYR 4 11 1.57 1 A TYR 6 -172.03 139.68 2 A LYS 3 -179.96 136.62 2 A GLU 12 -102.80 69.21 3 A LYS 3 -174.58 137.05 3 A GLU 12 -117.42 78.90 8 A LYS 3 -178.73 132.65 8 A GLU 12 -68.13 65.67 10 Structure Ensemble of the 14-residue peptide RG-KWTY-NG-ITYE-GR (MBH12) 1 N N DE NOVO PROTEIN beta-hairpin, DE NOVO PROTEIN 1K43 PDB 1 1K43 1 14 1K43 1 14 1K43 A 1 1 14 2 anti-parallel A TRP 4 A TRP 4 A TYR 6 A TYR 6 A ILE 9 A ILE 9 A TYR 11 A TYR 11
