Copper in the structure of Crystal Structure of the Double Mutant D44A D45A Plastocyanin From Phormidium Laminosum (pdb 3bqv)

The binding sites of Copper atom in the structure of Crystal Structure of the Double Mutant D44A D45A Plastocyanin From Phormidium Laminosum (pdb code 3bqv). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 3bqv structure was solved by R.FROMME, Y.S.BUKHMAN-DERUYTER, H.MI, P.FROMME, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-1.5 Space group P212121 a (A) 33.322 b (A) 33.778 c (A) 78.026 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.5 Rfree (%) 24.5 Copper Binding Sites: Copper binding site 1 out of 1 in 3bqv Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 3bqv.
