NMR Refinement
Method	Details	Software
torsion angle dynamics, DGSA-distance geometry simulated annealing	Initial structure ensemble was calculated by semi-automated NOESY assignment by CYANA. The assignments were manually verified in Sparky and final structure annealing was performed in CYANA. Structure and restraints from CYANA were imported in Xplor-NIH for explicit water refinement.
