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. ; _pdbx_nmr_refine.software_ordinal 1 # _pdbx_nmr_ensemble.entry_id 1K43 _pdbx_nmr_ensemble.conformers_calculated_total_number 50 _pdbx_nmr_ensemble.conformers_submitted_total_number 10 _pdbx_nmr_ensemble.conformer_selection_criteria 'structures with the lowest energy' _pdbx_nmr_ensemble.average_constraints_per_residue ? _pdbx_nmr_ensemble.average_constraint_violations_per_residue ? _pdbx_nmr_ensemble.maximum_distance_constraint_violation ? _pdbx_nmr_ensemble.average_distance_constraint_violation ? _pdbx_nmr_ensemble.maximum_upper_distance_constraint_violation ? _pdbx_nmr_ensemble.maximum_lower_distance_constraint_violation ? _pdbx_nmr_ensemble.distance_constraint_violation_method ? _pdbx_nmr_ensemble.maximum_torsion_angle_constraint_violation ? _pdbx_nmr_ensemble.average_torsion_angle_constraint_violation ? _pdbx_nmr_ensemble.torsion_angle_constraint_violation_method ? # _pdbx_nmr_representative.entry_id 1K43 _pdbx_nmr_representative.conformer_id 6 _pdbx_nmr_representative.selection_criteria 'lower rmsd with respect to mean' # loop_ _pdbx_nmr_software.name _pdbx_nmr_software.version _pdbx_nmr_software.classification _pdbx_nmr_software.authors _pdbx_nmr_software.ordinal XwinNMR 2.6 collection Bruker 1 XwinNMR 2.6 'data analysis' Bruker 2 DYANA 1.5 'structure solution' 'Guntert, P. et al.' 3 GROMOS 96 refinement 'van Gunsteren' 4 # _exptl.entry_id 1K43 _exptl.method 'SOLUTION NMR' _exptl.crystals_number ? # _exptl_crystal.id 1 _exptl_crystal.density_meas ? _exptl_crystal.density_Matthews ? _exptl_crystal.density_percent_sol ? _exptl_crystal.description ? # _diffrn.id 1 _diffrn.ambient_temp ? _diffrn.ambient_temp_details ? _diffrn.crystal_id 1 # _diffrn_radiation.diffrn_id 1 _diffrn_radiation.wavelength_id 1 _diffrn_radiation.pdbx_monochromatic_or_laue_m_l M _diffrn_radiation.monochromator ? _diffrn_radiation.pdbx_diffrn_protocol 'SINGLE WAVELENGTH' _diffrn_radiation.pdbx_scattering_type ? # _diffrn_radiation_wavelength.id 1 _diffrn_radiation_wavelength.wavelength . _diffrn_radiation_wavelength.wt 1.0 # _struct.entry_id 1K43 _struct.title '10 Structure Ensemble of the 14-residue peptide RG-KWTY-NG-ITYE-GR (MBH12)' _struct.pdbx_model_details ? _struct.pdbx_CASP_flag ? _struct.pdbx_model_type_details ? # _struct_keywords.entry_id 1K43 _struct_keywords.pdbx_keywords 'DE NOVO PROTEIN' _struct_keywords.text 'beta-hairpin, DE NOVO PROTEIN' # _struct_asym.id A _struct_asym.pdbx_blank_PDB_chainid_flag N _struct_asym.pdbx_modified N _struct_asym.entity_id 1 _struct_asym.details ? # _struct_biol.id 1 # _struct_sheet.id A _struct_sheet.type ? _struct_sheet.number_strands 2 _struct_sheet.details ? # _struct_sheet_order.sheet_id A _struct_sheet_order.range_id_1 1 _struct_sheet_order.range_id_2 2 _struct_sheet_order.offset ? _struct_sheet_order.sense anti-parallel # loop_ _struct_sheet_range.sheet_id _struct_sheet_range.id _struct_sheet_range.beg_label_comp_id _struct_sheet_range.beg_label_asym_id _struct_sheet_range.beg_label_seq_id _struct_sheet_range.pdbx_beg_PDB_ins_code _struct_sheet_range.end_label_comp_id _struct_sheet_range.end_label_asym_id _struct_sheet_range.end_label_seq_id _struct_sheet_range.pdbx_end_PDB_ins_code _struct_sheet_range.beg_auth_comp_id _struct_sheet_range.beg_auth_asym_id _struct_sheet_range.beg_auth_seq_id _struct_sheet_range.end_auth_comp_id _struct_sheet_range.end_auth_asym_id _struct_sheet_range.end_auth_seq_id A 1 TRP A 4 ?
