NMR Refinement
Method 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.
Details 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.
