Copper in the structure of Crystallographic Analysis Of Oxygenated and Deoxygenated States of Arthropod Hemocyanin Shows Unusual Differences (pdb 1oxy)

The binding sites of Copper atom in the structure of Crystallographic Analysis Of Oxygenated and Deoxygenated States of Arthropod Hemocyanin Shows Unusual Differences (pdb code 1oxy). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 1oxy structure was solved by H.TON-THAT, K.MAGNUS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 6.0-2.4 Space group H32 a (A) 117.240 b (A) 117.240 c (A) 285.860 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 17.1 Rfree (%) n/a Copper Binding Sites: Copper binding site 1 out of 2 in 1oxy Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Copper in the PDB 1oxy.
