NMR Refinement
MethodDetailsSoftware
simulated annealingThe structures are based on a total of 2848 restraints, 2248 are NOE-derived distance constraints, 299 dihedral angle restraints,50 distance restraints from hydrogen bonds, 205 Ca/Cb constraints, 96 coupling constant constraints. Additionally, a ramachandran conformational database and radius of gyration target function was used during the refinement.XwinNMR
