Details Zinc-ligand bond lengths were constrained as follows: Zn-S(Cys): 2.30 angstroms Zn-N(His): 2.00 angstroms The ligand configuration around the zinc ion was constrained to tetrahedral geometry by the following constraints: assign (resid 20 and name SG) (resid 25 and name SG) 3.76 0.20 0.20 assign (resid 20 and name SG) (resid 44 and name SG) 3.76 0.20 0.20 assign (resid 25 and name SG) (resid 44 and name SG) 3.76 0.20 0.20 assign (resid 20 and name SG) (resid 38 and name NE2) 3.52 0.20 0.20 assign (resid 25 and name SG) (resid 38 and name NE2) 3.52 0.20 0.20 assign (resid 44 and name SG) (resid 38 and name NE2) 3.52 0.20 0.20 Residues 4-63 were included in the structure calculations.
