NMR Refinement
Method CNS, dynamical annealing protocal with molecular dynamic scheme of torsion,torsion,cartesian. Initially only distance restraints from the three Cys to the zinc were restrained. Eventually the His was also restrained and angle restraints added to make the site tetrahedral.
Details 442 NOE restraints, 15 Torsional angle restraints. 15 zinc site restraints, 64 Carbon chemical shifts, and 174 proton chemical restraints.
