NMR Refinement
Method	Details	Software
Simulate annealing, torsion angle dynamics	A total of 1639 upper distance limits (of which 1431 meaningful), 31 dihedral phi angle constraints and 48 psi angle constraints were measured and used in the structural calculations. 5 stereospecific assignments were also obtained from the analysis of HNHB spectra and 11 through the program GLOMSA.
