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 obteined from TALOS. The assignments were validated using AVS software. FInal structure factors determined using PSVS: ordered residues: alpha helices- 33.44, 67-70, beta strands- 22-27, 11-17, 78-82, 51-55, 58-59. Ramachandran statistics for ordered residues: 89.1% most favoured regions, 10.9% additionally favoured regions. Procheck scores for ordered residues (RAW/Z): phi/psi -0.43/-1.38, all -0.18/-1.06, MolProbity clashscores- 21.46/-2.16. RPF score for goodness fit to the NOESY data: Recall-0.998, Precision-0.93, final dp-score-0.869	CNS
