ARIA protocol (Nilges, M. et al., (1997) J. Mol. Biol. 269, 408-422) was used to deal with ambiguous distance restraints and for some NOE assignments. | The ParG structure is based on 2230 ambiguous NOE restraints, 82 hydrogen bond restraints, and 144 CSI-based dihedral angle restraints. N-terminal region of ParG (1-32) is unstructured. The C-terminal region (33-76) is structured. | NMRPipe |
