NMR Refinement
Method	Details	Software
simulated annealing	Structure determination was performed by CYANA and AUTOSTRUCTURE in parallel using NOE-based constraints and PHI and PSI dihedral angle constraints. Consensus peak assignments generated from these parallel runs were selected and used for further refinement with CYANA, the RDC constraints were added at later stages. A total of 20 conformers out of 100 conformers with the lowest target function were selected for refinement with CNS using CNS water bath refinement.	CNS
