Cobalt in the structure of Crystal Structure of Dna Sheared Tandem G-A Base Pairs (pdb 1d9r)

The binding sites of Cobalt atom in the structure of Crystal Structure of Dna Sheared Tandem G-A Base Pairs (pdb code 1d9r). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1d9r structure was solved by Y.-G.GAO, H.ROBINSON, R.SANISHVILI, A.JOACHIMIAK, A.H.-J.WANG, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-1.5 Space group C2221 a (A) 22.711 b (A) 67.216 c (A) 72.504 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 23.4 Rfree (%) 27.8 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 1d9r Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1d9r.
