The binding sites of Copper atom in the structure of Design Of Disulfide-Linked Thioredoxin Dimers and Multimers Through Analysis of Crystal Contacts (pdb code 2eiq). This binding sites where shown with 5.0 Angstroms radius around Copper atom. The 2eiq structure was solved by M.KOBAYASHI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
Resolution (A) | 41.6-1.9 | Space group | C121 | a (A) | 89.209 | b (A) | 49.557 | c (A) | 59.427 | alpha (°) | 90.00 | beta (°) | 113.33 | gamma (°) | 90.00 | Rfactor (%) | 18.4 | Rfree (%) | 21.8 |
