NMR Refinement
Method	Details	Software
simulated annealing	Structures were refined by using data imputation (. Cano, C., Brunner, Baskaran, K., K. Elsner, R., Munte, C. E. and Kalbitzer, H. R. (2009) Protein structure calculation with data imputation: the use of substitute restraints. J. Biomol. NMR 45, 397-411) and refinement in explicut water (Linge, J.P., Williams, M.A., Spronk, C.A.E.M., Bonvin, A.M.J.J. and Nilges, M. (2003). Refinement of protein structures in explicit solvent. Proteins 50, 496-506).	AUREMOL

Additional NMR Experimental Information
Details	The structure has been determined combining experimental restraints (J-couplings, Noe distances, Hydrogen Bonds and RDCs) with dihedral angles obtained with TALOS and with additional substitute restraints (Noes, Hydrogen bonds and dihedral angles)
