NMR Refinement
Method	Details	Software
simulated annealing	The structures are based on 1692 NOE-derived distance restraints, of which 1055 distance restraints are non-redundant. 407 restraints are intraresidue, 212 are sequential, 226 are mediumrange (i-j < 5) and 210 are long-range (i-j > 4)	XwinNMR
