NMR Refinement
Method	Details	Software
The structures are based on a total of 2377 restraints. Among them, 2107 are NOE-derived distance constraints, 192 TALOS-derived dihedral angle restraints, and 78 restraints from hydrogen bonds.		XwinNMR

NMR Ensemble Information
Conformer Selection Criteria	structures with the least restraint violations, structures with the lowest energy
Conformers Calculated Total Number	50
Conformers Submitted Total Number	20

Additional NMR Experimental Information
Details	The structure was refined by adding 221 NOE-derived distance constraints and by revising a few previous NOE assignments.
