Cobalt in the structure of Crystal Structure Of Arachidonic Acid Bound in the Cyclooxygenase Active Site of Pghs-1 (pdb 1diy)

The binding sites of Cobalt atom in the structure of Crystal Structure Of Arachidonic Acid Bound in the Cyclooxygenase Active Site of Pghs-1 (pdb code 1diy). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 1diy structure was solved by M.G.MALKOWSKI, S.L.GINELL, W.L.SMITH, R.M.GARAVITO, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 9.0-3.0 Space group P6522 a (A) 182.100 b (A) 182.100 c (A) 103.640 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 21.5 Rfree (%) 29 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 1diy Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 1diy. 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: Gln203, A: His207, A: His388, A: Val447, A: Coh601, conact list: Atom Atom Distance (A) Co OE1 A:Gln203 4.17 Co NE2 A:His207 4.98 Co CE1 A:His207 4.88 Co NE2 A:His388 2.16 Co ND1 A:His388 4.28 Co CD2 A:His388 3.27 Co CE1 A:His388 3.09 Co CG A:His388 4.39 Co CG2 A:Val447 4.74 Co CG1 A:Val447 4.45 Co C2D A:Coh601 4.35 Co NC A:Coh601 2.02 Co CHB A:Coh601 3.44 Co CHC A:Coh601 3.34 Co C3D A:Coh601 4.26 Co NA A:Coh601 1.99 Co CHA A:Coh601 3.32 Co C2A A:Coh601 4.35 Co C1D A:Coh601 3.03 Co C4A A:Coh601 3.06 Co C4B A:Coh601 3.02 Co C3A A:Coh601 4.40 Co C4C A:Coh601 3.08 Co C2B A:Coh601 4.34 Co C1C A:Coh601 3.01 Co C2C A:Coh601 4.28 Co ND A:Coh601 1.95 Co CHD A:Coh601 3.45 Co C1B A:Coh601 3.07 Co NB A:Coh601 1.95 Co C3C A:Coh601 4.30 Co C3B A:Coh601 4.31 Co CO A:Coh601 0.00 Co C4D A:Coh601 2.99 Co C1A A:Coh601 3.02 interactive model:
