Cobalt in the structure of Crystal Structure of Dna Sheared Tandem G A Base Pairs (pdb 1d8x)

The binding sites of Cobalt atom in the structure of Crystal Structure of Dna Sheared Tandem G A Base Pairs (pdb code 1d8x). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1d8x 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) 20.0-1.2 Space group C121 a (A) 62.784 b (A) 35.685 c (A) 22.466 alpha (°) 90.00 beta (°) 104.38 gamma (°) 90.00 Rfactor (%) 18.8 Rfree (%) 24.6 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 1d8x Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1d8x. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Cobalt atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Dt6, A: Dg7, A: Nco21, A: Hoh114, A: Hoh167, A: Hoh170, A: Hoh209, conact list: Atom Atom Distance (A) Co OP2 A:Dt6 4.12 Co C6 A:Dg7 4.96 Co N7 A:Dg7 4.37 Co O6 A:Dg7 4.13 Co N1 A:Nco21 1.97 Co N6 A:Nco21 1.97 Co CO A:Nco21 0.00 Co N3 A:Nco21 1.99 Co N2 A:Nco21 2.00 Co N5 A:Nco21 2.00 Co N4 A:Nco21 2.00 Co O A:Hoh114 4.36 Co O A:Hoh167 3.44 Co O A:Hoh170 4.32 Co O A:Hoh209 3.54 interactive model:
