NMR Refinement
Method torsion angle dynamics simulated annealing
Details The structures are based on a total of 1419 conformationally-restricting NOE-derived distance restraints, 210 dihedral angle restraints, and 78 hydrogen bond restraints. Initial structure determination was performed by torsion angle dynamics (DYANA). The final structures submitted were refined by simulated annealing (XPLOR).

Additional NMR Experimental Information
1 The structure was determined using triple-resonance NMR spectroscopy. Automatic backbone resonance assignments were made using AUTOASSIGN. Automatic NOESY assignments as well as distance and hydrogen bond restraints were determined using the AUTOSTRUCTURE program. Dihedral angle restraints were determined using HYPER and TALOS. Backbone conformations for residues 1-5, 25-26, 66, 101-108 are not well-defined [S(phi) + S(psi) < 1.8] in this solution NMR structure.
