NMR Refinement
Method	Details	Software
DGSA-distance geometry simulated annealing	Structures were calculated on the basis of 3667 total constraints. 2943 of these constraints were NOE-derived distances of which 197 were intermolecular NOEs; 348 dihedral angle restraints and 188 hydrogen bonds	TopSpin

NMR Ensemble Information
Conformer Selection Criteria	structures with the least restraint violations
Conformers Calculated Total Number	256
Conformers Submitted Total Number	20
Representative Model	1 (closest to the average)

Additional NMR Experimental Information
Details	standard heteronuclear methods were used to assign resonances and determine the constraints
