NMR Refinement
Method hybrid distance geometry/simulated annealing followed by restrained molecular dynamics.
Details Complete 1H resonance assignments were obtained using standard 2D homonuclear NMR methods. Distance restraints were derived from analysis of a 2D NOESY spectrum (250ms mixing time); HN-Ha coupling constants were obtained from analysis of a DQF-COSY spectrum acquired in water; and HaHb values were obtained from analysis of a COSY-35 spectrum acquired in D2O. Structures were calculated from a total of 119 NOE-derived (including 46 long-range) distance restraints and 16 dihedral angle restraints. Structures satisfy the experimental data very well with no distance or dihedral angle violations greater than 0.1 angstrom or 1 degree, respectively.
