NMR Refinement
Method
Details
Software
Simulated annealing using cartesian and torsion angle dynamics.
NOE assignments, distance restraint calibrations, and initial structures were made using ARIA 1.2. Final structure refinement was done using Xplor-NIH with the NOE derived distance restraints, 126 phi/psi dihedral angles, 48 HNHA coupling constants, 33 hydrogen bonds, 80 dipolar couplings, 57 T1/T2 relaxation ratios, and non-crystallographic dimer symmetry restraints (numbers are per monomer). Anisotropy tensors were refined simultaneously with the structure.
