Nickel in the structure of Carbon Monoxide Dehydrogenase From Carboxydothermus Hydrogenoformans- Dtt Reduced State (pdb 1su7)

The binding sites of Nickel atom in the structure of Carbon Monoxide Dehydrogenase From Carboxydothermus Hydrogenoformans- Dtt Reduced State (pdb code 1su7). This binding sites where shown with 5.0 Angstroms radius around Nickel atom. The 1su7 structure was solved by H.DOBBEK, V.SVETLITCHNYI, J.LISS, O.MEYER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-1.1 Space group C121 a (A) 111.616 b (A) 73.825 c (A) 70.832 alpha (°) 90.00 beta (°) 111.17 gamma (°) 90.00 Rfactor (%) 13.8 Rfree (%) 20.7 Nickel Binding Sites: Nickel binding site 1 out of 1 in 1su7 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Nickel in the PDB 1su7.
