NMR Refinement
Method	Details	Software
DGSA-distance geometry simulated annealing	the structures were calculated using an ab-initio simulated annealing protocol within the CNS/Xplor-NIH programs with PARALLHDG v5.3 parameter set and PROLSQ non-bonded energy function. Cartesian and torsion angle dynamics were used to refine the structures.	NMRPipe
