Cobalt in the structure of Anaerobic Cobalt Chelatase (Cbik) From Salmonella Typhimurium in Complex With Metalated Tetrapyrrole (pdb 2xwp)

The binding sites of Cobalt atom in the structure of Anaerobic Cobalt Chelatase (Cbik) From Salmonella Typhimurium in Complex With Metalated Tetrapyrrole (pdb code 2xwp). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 2xwp structure was solved by D.LADAKIS, A.A.BRINDLEY, E.DEERY, M.J.WARREN, R.W.PICKERSGILL, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 44.8-1.9 Space group P6322 a (A) 110.630 b (A) 110.630 c (A) 89.530 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 19.42 Rfree (%) 23.928 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 2xwp Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 2xwp.
