Details The models are based on a total of 1993 constraints (12.5 constraints per residue): 1793 NOE-derived distance constraints; 116 TALOS-derived dihedral angle constraints; and 84 hydrogen bond constraints, based on the identification of slow exchange amide protons in D2O NOESY and TOCSY experiments, on characteristic NOE patterns for alpha-helices and beta-sheets, and on the proximity and orientation of potential hydrogen bond partners in annealed structures. The final set of 20 structures contains no violations of NOE distance constraints greater than 0.15 angstroms and no violations of dihedral angle constraints greater than 5 degrees.
