Copper in the structure of Azide-Bound Yeast Cu(II)/Zn Superoxide Dismutase Room Temperature (298K) Structure (pdb 1yaz)

The binding sites of Copper atom in the structure of Azide-Bound Yeast Cu(II)/Zn Superoxide Dismutase Room Temperature (298K) Structure (pdb code 1yaz). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1yaz structure was solved by P.J.HART, M.M.BALBIRNIE, N.L.OGIHARA, A.M.NERSISSIAN, M.S.WEISS, J.S.VALENTINE, D.EISENBERG, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 90.0-1.7 Space group H32 a (A) 119.375 b (A) 119.375 c (A) 74.543 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 16.9 Rfree (%) 20.8 Copper Binding Sites: Copper binding site 1 out of 1 in 1yaz Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1yaz.
