Copper in the structure of Crystal Structure Of A New Type of Nadph-Dependent Quinone Oxidoreductase (QOR2) From Escherichia Coli (pdb 2zcu)

The binding sites of Copper atom in the structure of Crystal Structure Of A New Type of Nadph-Dependent Quinone Oxidoreductase (QOR2) From Escherichia Coli (pdb code 2zcu). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 2zcu structure was solved by I.K.KIM, H.S.YIM, M.K.KIM, D.W.KIM, Y.M.KIM, S.S.CHA, S.O.KANG, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 19.7-1.8 Space group P3221 a (A) 81.685 b (A) 81.685 c (A) 76.801 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 23.6 Rfree (%) 27.8 Copper Binding Sites: Copper binding site 1 out of 1 in 2zcu Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 2zcu. 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: Glu276, A: His280, A: Hoh1226, A: Hoh1399, conact list: Atom Atom Distance (A) Cu O A:Glu276 4.71 Cu OE1 A:Glu276 4.16 Cu OE2 A:Glu276 2.55 Cu CD A:Glu276 3.30 Cu CG A:Glu276 3.81 Cu NE2 A:His280 2.26 Cu ND1 A:His280 3.86 Cu CD2 A:His280 3.40 Cu CE1 A:His280 2.71 Cu CG A:His280 4.22 Cu O A:Hoh1226 2.68 Cu O A:Hoh1399 4.41 interactive model:
