NMR Refinement
Method	Details	Software
simulated annealing molecular dynamics torsion angle dynamics	Structure calculations were performed using the package ARIA 1.1 (Ambiguous Restraints in Iterative Assignment)> Final structures are based on 719 unambiguous NOE-derived distance consraints, 6 sets of ambiguous NOE-derived distance constraints and 28 additional dihedral angle restraints.
