NMR Refinement
Method restrained molecular dynamics; simulated annealing
Details The average structure is based on superposition of nine converged structures after refinement. The average RMS deviation between the ensemble and the average structure is 1.8 Angstrom. A total of 266 NOE-derived distance constraints, 164 dihedral restraints and 48 distance restraints from hydrogen bonds were used in the refinement
