Copper in the structure of Crystal Structure Of The Spinach Plastocyanin Mutants G8D/K30C/T69C And K30C/T69C- A Study Of The Effect on Crystal Packing and Thermostability From the Introduction of A Novel Disulfide Bond (pdb 1teg)

The binding sites of Copper atom in the structure of Crystal Structure Of The Spinach Plastocyanin Mutants G8D/K30C/T69C And K30C/T69C- A Study Of The Effect on Crystal Packing and Thermostability From the Introduction of A Novel Disulfide Bond (pdb code 1teg). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1teg structure was solved by M.OKVIST, F.JACOBSON, H.JANSSON, O.HANSSON, L.SJOLIN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 45.2-2.0 Space group P3221 a (A) 52.196 b (A) 52.196 c (A) 126.928 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 28.7 Rfree (%) 30.4 Copper Binding Sites: Copper binding site 1 out of 2 in 1teg Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1teg.
