NMR Refinement
Method	Details	Software
simulated annealing, distance geometry	The structures are based on a total of 1321 restraints: 1245 are NOE-derived distance constraints, 57 are dihedral angle restraints and 19 distance restraints are from hydrogen bonds.	VNMR

NMR Ensemble Information
Conformer Selection Criteria	structures with acceptable covalent geometry,structures with the least restraint violations
Conformers Calculated Total Number	100
Conformers Submitted Total Number	43
Representative Model	1 (closest to the average)

Additional NMR Experimental Information
Details	The structure was determined using triple-resonance NMR spectroscopy. Hydrogen bond restraints were derived from protection factors measured by H/D exchange. Torsion angle restraints were derived from J-coupling data (HNHA experiment) and from TALOS predictions.
