NMR Refinement
Method	Details	Software
simulated annealing	the structures are based on a total of 1309 restraints, 1211 are NOE-derived distance constraints, 56 dihedral angle restraints, 42 distance restraints from hydrogen bonds. N-terminal residues 632-646 are not defined by NMR restraints and excluded from the coordinate file.	UXNMR
