NMR Refinement
Method	Details	Software
distance geometry and simulated annealing	structures were calculated with: 1806 NOE-derived destance constriants (no intra-residue NOEs used), 28 hydrogen bonds, 135 dihedral restraints, 276 residual dipolar couplings. Residues 1-3 and 79-84 are disordered. Superimposition of structures is from residues 4-78.	XwinNMR
