NMR Refinement
Method	Details	Software
distance geometry, simulated annealing	Additional comments about the NMR refinement can be placed here, e.g. the structures are based on a total of 499 restraints, 449 are NOE-derived distance constraints, 27 dihedral angle restraints,14 distance restraints from hydrogen bonds, and 9 distance restraints from disulfide bonds.
