Copper in the structure of Reduced Bovine Superoxide Dismutase At pH 5.0 Complexed With Azide (pdb 1sxz)

The binding sites of Copper atom in the structure of Reduced Bovine Superoxide Dismutase At pH 5.0 Complexed With Azide (pdb code 1sxz). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1sxz structure was solved by M.FERRARONI, W.R.RYPNIEWSKI, B.BRUNI, P.ORIOLI, K.S.WILSON, S.MANGANI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-2.0 Space group C2221 a (A) 104.600 b (A) 197.500 c (A) 50.800 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 16.6 Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 2 in 1sxz Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1sxz.
