Method	Details	Software
simulated annealing	The structure was obtained using triple resonance NMR spectroscopy. GFT-NMR experiments were used for backbone assignments. Automated NOESY assignments were made using AUTOSTRUCTURE and CYANA-2.1. Dihedral angle constraints were obtained from TALOS. The assignments were validated using AVS software. Final structure factors determined using PSVS: ordered residues: 29-33, 15-21, 89-94, 57-62, 39-50, 79-82. Ramachandran statistics for ordered residues: Most favored region: 84.4%, additionally favored region: 15.6%, generously aloowed: 0.1%. Procheck scores for ordered residues (RAW/Z): Phi/psi -0.51/-1.69, all -0.33/-1.95, MolProbity clash scores (RAW/Z) - 15.41/-1.12. RPF scores for the goodness fit to NOESY data: Recall-0.993, Precision-0.878, F-measure-0.932, final dp score-0.756.	CNS
