    Method TORSION ANGLE DYNAMICS
    Details THE STRUCTURES ARE BASED ON A TOTAL OF 1582 NON-TRIVIAL UPPER-LIMIT DISTANCE CONSTRAINTS (332 LONG-RANGE, 560 MEDIUM-RANGE, 372 SEQUENTIAL AND 318 INTRARESIDUE), DERIVED FROM 3288 ASSIGNED NOES FROM 4 2D AND 3D SPECTRA. THIS CORRESPONDS TO AN AVERAGE OF 19.8 CONSTRAINTS/RESIDUE. NO ADDITIONAL CONSTRAINTS WERE INCLUDED. STRUCTURES WERE GENERATED USING THE ANNEAL FUNCTION OF THE PROGRAM DYANA 1.5, WITH 8000 TORSION ANGLE DYNAMICS STEPS FOR EACH STRUCTURE. THE AVERAGE DYANA TARGET FUNCTION FOR THE 30 CONFORMERS WAS 0.68 +/- 0.11. THE AVERAGE BACKBONE ATOMIC RMSD TO THE MEAN STRUCTURE FOR RESIDUES 4-81 IS 0.43 +/- 0.08 ANGSTROMS, AND 0.86 +/- 0.09 FOR ALL NON-HYDROGEN ATOMS (RESIDUES 4-81).
