NMR Refinement
Method	Details	Software
molecular dynamics matrix relaxation	The structures are based on a total of 311 NOE-derived distance constraints obtained from a complete relaxation matrix refinement. The structures were calculated by using restrained molecular dynamics with explicit solvent, and applying the particle Mesh Ewald method	DYANA
