Cobalt in the structure of Refined Crystal Structure of Type III Chloramphenicol Acetyltransferase At 1.75 Angstroms Resolution (pdb 3cla)

The binding sites of Cobalt atom in the structure of Refined Crystal Structure of Type III Chloramphenicol Acetyltransferase At 1.75 Angstroms Resolution (pdb code 3cla). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 3cla structure was solved by A.G.W.LESLIE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 6.0-1.8 Space group H32 a (A) 107.600 b (A) 107.600 c (A) 123.600 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 15.7 Rfree (%) n/a Cobalt Binding Sites: Cobalt binding site 1 out of 2 in 3cla Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 3cla.
