Cobalt in the structure of A Closer Look At The Active Site Of Gamma-Carbonic Anhydrases: High Resolution Crystallographic Studies of the Carbonic Anhydrase From Methanosarcina Thermophila (pdb 1qrf)

The binding sites of Cobalt atom in the structure of A Closer Look At The Active Site Of Gamma-Carbonic Anhydrases: High Resolution Crystallographic Studies of the Carbonic Anhydrase From Methanosarcina Thermophila (pdb code 1qrf). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1qrf structure was solved by T.M.IVERSON, B.E.ALBER, C.KISKER, J.G.FERRY, D.C.REES, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.6 Space group P213 a (A) 82.608 b (A) 82.608 c (A) 82.608 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.5 Rfree (%) 22.9 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 1qrf Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1qrf.
