Cobalt in the structure of X-Ray Crystal Structure of Cobalt-Bound F93I/F95M/W97V Carbonic Anhydrase (Caii) Variant (pdb 1fqr)

The binding sites of Cobalt atom in the structure of X-Ray Crystal Structure of Cobalt-Bound F93I/F95M/W97V Carbonic Anhydrase (Caii) Variant (pdb code 1fqr). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1fqr structure was solved by J.D.COX, J.A.HUNT, K.M.COMPHER, C.A.FIERKE, D.W.CHRISTIANSON, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-2.0 Space group P1211 a (A) 42.000 b (A) 42.300 c (A) 72.400 alpha (°) 90.00 beta (°) 103.10 gamma (°) 90.00 Rfactor (%) 21.6 Rfree (%) 27.5 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 1fqr Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1fqr. 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: Hoh301, A: Hoh302, conact list: Atom Atom Distance (A) Co NE2 A:His94 2.12 Co ND1 A:His94 4.23 Co CD2 A:His94 3.02 Co CE1 A:His94 3.16 Co CG A:His94 4.20 Co NE2 A:His96 2.21 Co ND1 A:His96 4.35 Co CD2 A:His96 2.97 Co CE1 A:His96 3.35 Co CG A:His96 4.21 Co OE1 A:Glu106 3.87 Co CD A:Glu106 4.65 Co NE2 A:His119 3.99 Co CB A:His119 3.66 Co ND1 A:His119 2.00 Co CD2 A:His119 4.17 Co CE1 A:His119 2.80 Co CG A:His119 3.15 Co CB A:Thr199 4.88 Co CG2 A:Thr199 4.76 Co OG1 A:Thr199 3.79 Co O A:Hoh301 1.89 Co O A:Hoh302 3.81 interactive model:
