Copper in the structure of The Crystal Structures of Reduced Pseudoazurin From Alcaligenes Faecalis S-6 At Two pH Values (pdb 1pza)

The binding sites of Copper atom in the structure of The Crystal Structures of Reduced Pseudoazurin From Alcaligenes Faecalis S-6 At Two pH Values (pdb code 1pza). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1pza structure was solved by K.PETRATOS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-1.8 Space group P65 a (A) 49.900 b (A) 49.900 c (A) 99.100 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) n/a Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 1 in 1pza Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1pza. 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: Pro80, A: His81, A: Met86, conact list: Atom Atom Distance (A) Cu O A:Gly39 3.83 Cu C A:Gly39 4.37 Cu NE2 A:His40 4.23 Cu N A:His40 4.33 Cu CB A:His40 3.52 Cu ND1 A:His40 2.16 Cu CD2 A:His40 4.27 Cu C A:His40 4.68 Cu CE1 A:His40 3.12 Cu CG A:His40 3.16 Cu CA A:His40 3.57 Cu N A:Asn41 4.67 Cu CB A:Cys78 3.18 Cu SG A:Cys78 2.17 Cu CA A:Cys78 4.55 Cu CB A:Pro80 4.83 Cu CD A:Pro80 4.96 Cu CG A:Pro80 4.38 Cu NE2 A:His81 4.34 Cu N A:His81 4.18 Cu CB A:His81 3.55 Cu ND1 A:His81 2.29 Cu CD2 A:His81 4.39 Cu CE1 A:His81 3.23 Cu CG A:His81 3.26 Cu CA A:His81 4.51 Cu CB A:Met86 4.68 Cu CE A:Met86 3.65 Cu CG A:Met86 4.32 Cu SD A:Met86 2.91 interactive model:
