torsion angle dynamicsA total of 861 restraints were used for the final calculations, including 781 NOEs (of which 384 were long-range NOEs), 30 hydrogen bond restraints, 50 torsion angle restraints and 18 restraints for the two Zn2+ binding sites. The latter were derived from analysis of high resolution crystal structures containing bound Zn2+ ions that are coordinated by three cysteines and one histidineVNMR
