Method | Details | Software |
torsion angle dynamics | The CANDID software was used for initial automatic NOE assignment. Structures are based on 1629 NOE-derived upper distance constraints (47 intra residue), 136 distance restraints from hydrogen bonds, refinement against 129 J(HNHA) coupling constants and 234 PHI/PSI dihedral angle constraints from TALOS. | VNMR |
