NMR Refinement
Method	Details	Software
distance geometry simulated annealing energy minimization	The 20 structures are based on a total of 289 restraints, 279 are NOE-derived distance constraints, 4 are used for hydrogen bonds modelling and 6 (i.e. 2x3) are used for disulfide bridge modelling. No dihedral angle restraints used.	DYANA
