Copper in the structure of Crystal Structure of Nadph-Dependent Quinone Oxidoreductase QOR2 Complexed With Nadph From Escherichia Coli (pdb 2zcv)

The binding sites of Copper atom in the structure of Crystal Structure of Nadph-Dependent Quinone Oxidoreductase QOR2 Complexed With Nadph From Escherichia Coli (pdb code 2zcv). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 2zcv 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) 19.5-2.3 Space group P3221 a (A) 81.284 b (A) 81.284 c (A) 77.506 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 21.7 Rfree (%) 29.8 Copper Binding Sites: Copper binding site 1 out of 1 in 2zcv Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 2zcv.
