NMR Refinement
Method	Details	Software
simulated annealing	The structures are based on a total of 2156 restraints, 1886 are NOE-derived distance constraints, 192 TALOS-derived dihedral angle restraints,78 distance restraints from hydrogen bonds. RESIDUES 1-14 ARE POORLY DEFINED BY THE EXPERIMENTAL DATA. THUS, NO MEANING SHOULD BE GIVEN TO THOSE RESIDUES' COORDINATES.	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
Representative Model	2 (closest to the average)

Additional NMR Experimental Information
Details	The structure was determined using triple-resonance NMR spectroscopy.
