NMR Refinement
Method	Details	Software
distance geometry and restrained molecular dynamics	Structures were calculated beginning with 1,000 random structures and incrementally adding distance constraints in four iterations. The final 30 structures with the lowest number of violations were subjected to RMD. The structures are based on a total of 700 distance constraints, 61 dihedral angle restraints.	CYANA
