NMR Refinement
Method restrained molecular dynamics and simulated annealing
Details The average structure is based on superposition of 17 converged structures after refinement. The average RMS deviation between the ensemble and the average structure is 1.9 Angstrom. A total of 268 NOE derived distance constraints, 171 dihedral restraints and 49 distance restraints from hydrogen bonds were used for refinement
