Copper in the structure of Oxygenated Hemocyanin (Subunit Type II) (pdb 1nol)

The binding sites of Copper atom in the structure of Oxygenated Hemocyanin (Subunit Type II) (pdb code 1nol). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1nol structure was solved by B.HAZES, W.G.J.HOL, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-2.4 Space group R32 a (A) 117.002 b (A) 117.002 c (A) 117.002 alpha (°) 60.02 beta (°) 60.02 gamma (°) 60.02 Rfactor (%) 18.1 Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 2 in 1nol Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1nol.
