NMR Refinement
Method	Details	Software
torsion angle dynamics, molecular dynamics	Structure determination was performed iteratively using CYANA (Automated NOESY Assignments). A total of 20 structures out of 100 with lowest target function from the final CYANA calculation were taken and refined by restrained molecular dynamics/energy minimization in explicit water (CNS) after adding 15% to the upper boundary limit. The final set of structures contained no dihedral violations greater than 1 degree and only 4 distance violations total that were greater than 0.05 Angstrom.	CYANA
