Copper in the structure of Reduced Mutant P80I Pseudoazurin From A. Faecalis (pdb 7paz)

The binding sites of Copper atom in the structure of Reduced Mutant P80I Pseudoazurin From A. Faecalis (pdb code 7paz). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 7paz structure was solved by E.T.ADMAN, C.A.P.LIBEU, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 26.0-2.0 Space group P65 a (A) 50.790 b (A) 50.790 c (A) 98.250 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 20.6 Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 1 in 7paz Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 7paz. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Copper atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Gly39, A: His40, A: Asn41, A: Cys78, A: Ile80, A: His81, A: Met86, conact list: Atom Atom Distance (A) Cu O A:Gly39 3.45 Cu C A:Gly39 4.29 Cu NE2 A:His40 4.10 Cu N A:His40 4.37 Cu CB A:His40 3.44 Cu ND1 A:His40 2.04 Cu CD2 A:His40 4.17 Cu C A:His40 4.62 Cu CE1 A:His40 2.98 Cu CG A:His40 3.06 Cu CA A:His40 3.53 Cu N A:Asn41 4.54 Cu CB A:Cys78 3.24 Cu SG A:Cys78 2.15 Cu CA A:Cys78 4.64 Cu N A:Ile80 4.98 Cu CB A:Ile80 4.26 Cu CG2 A:Ile80 4.57 Cu C A:Ile80 4.65 Cu CA A:Ile80 4.84 Cu NE2 A:His81 4.17 Cu N A:His81 3.89 Cu CB A:His81 3.61 Cu ND1 A:His81 2.13 Cu CD2 A:His81 4.28 Cu CE1 A:His81 3.01 Cu CG A:His81 3.20 Cu CA A:His81 4.40 Cu CB A:Met86 4.87 Cu CE A:Met86 3.77 Cu CG A:Met86 4.57 Cu SD A:Met86 2.95 interactive model:
