*The total intermolecular NOEs include all unique and ambiguous NOEs identified from 3D 13C/15N-filtered 13C-edited NOESY-HSQC experiment and 13C-edited NOESY-HSQC experiment.
**The RMSD values were calculated for residues 5–44.
†
The values of Ramachandran statistics were calculated for residues 5–44. The C-terminal unstructured region is excluded from the analysis.
