Method Ab initio simulated annealing
Details The structure is based on 276 distance restraints, 240 derived from NOE, 33 metal cluster restraints from 113Cd HSQC TOCSY and 6 restraints from HN-S hydrogen bonds. A total of 27 dihedral angle restraints was applied, 13 phi, 10 chi1 and 4 Cys-Cd chi2 angles. Methylene protons for which no stereospecific assignment could be obtained were treated with the floating chirality procedure in XPLOR.
