Cobalt in the structure of X-Ray Analysis of Metal Substituted Human Carbonic Anhydrase II Derivatives (pdb 1rza)

The binding sites of Cobalt atom in the structure of X-Ray Analysis of Metal Substituted Human Carbonic Anhydrase II Derivatives (pdb code 1rza). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1rza structure was solved by K.HAKANSSON, A.WEHNERT, A.LILJAS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 1.9 Space group P1211 a (A) 42.700 b (A) 41.700 c (A) 73.000 alpha (°) 90.00 beta (°) 104.60 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 1rza Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1rza. 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: His94, A: His96, A: Glu106, A: His119, A: Thr199, A: Oxy500, A: Hoh263, A: Hoh292, A: Hoh318, A: Hoh389, conact list: Atom Atom Distance (A) Co NE2 A:His94 2.16 Co ND1 A:His94 4.25 Co CD2 A:His94 3.04 Co CE1 A:His94 3.15 Co CG A:His94 4.20 Co NE2 A:His96 2.15 Co ND1 A:His96 4.21 Co CD2 A:His96 3.12 Co CE1 A:His96 3.10 Co CG A:His96 4.25 Co OE1 A:Glu106 4.05 Co CD A:Glu106 4.92 Co NE2 A:His119 4.16 Co CB A:His119 3.59 Co ND1 A:His119 2.12 Co CD2 A:His119 4.23 Co CE1 A:His119 3.00 Co CG A:His119 3.17 Co OG1 A:Thr199 3.93 Co O1 A:Oxy500 3.46 Co O2 A:Oxy500 2.72 Co O A:Hoh263 2.06 Co O A:Hoh292 4.33 Co O A:Hoh318 3.86 Co O A:Hoh389 4.51 interactive model:
