NMR Refinement
MethodDetailsSoftware
distance geometry simulated annealing molecular dynamics matrix relaxationAdditional comments about the NMR refinement can be placed here, e.g. the structures are based on a total of 517 restraints, 466 are NOE-derived distance constraints, 22 dihedral angle restraints,51 distance restraints from hydrogen bonds.X-PLOR
