Copper in the structure of Crystal Structure of Reduced Bovine Erythrocyte Superoxide Dismutase At 1.9 Angstroms Resolution (pdb 1sxb)

The binding sites of Copper atom in the structure of Crystal Structure of Reduced Bovine Erythrocyte Superoxide Dismutase At 1.9 Angstroms Resolution (pdb code 1sxb). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1sxb structure was solved by W.R.RYPNIEWSKI, S.MANGANI, B.BRUNI, P.ORIOLI, M.CASATI, K.S.WILSON, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-2.0 Space group P212121 a (A) 47.710 b (A) 50.980 c (A) 147.820 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 2 in 1sxb Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1sxb.
