Method	Details	Software
Simulated annealing and TORSION ANGLE DYNAMICS	Chemical shift assignments were manually done. Automated NOESY assignment and structure ensemble calculation was performed with CYANA v.2.1. A total of 431 unassigned NOESY peaks with intensity greater than ~1% of the most intense NOESY peak were input to CYANA. CYANA assigned 403 of 431 (93.5%) peaks, of which 309 were used as distance constraints in the structure calculation.	1
