Cobalt in the structure of Structure of Helicobacter Pylori Peptide Deformylase in Complex With Inhibitor (pdb 2ew5)

The binding sites of Cobalt atom in the structure of Structure of Helicobacter Pylori Peptide Deformylase in Complex With Inhibitor (pdb code 2ew5). This binding sites where shown with 5.0 Angstroms radius around Cobalt atom. The 2ew5 structure was solved by J.CAI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 12.0-2.2 Space group P212121 a (A) 42.117 b (A) 52.970 c (A) 92.259 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.1 Rfree (%) 25.4 Cobalt Binding Sites: Cobalt binding site 1 out of 1 in 2ew5 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Cobalt in the PDB 2ew5. 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: Gln51, A: Gly95, A: Cys96, A: Leu97, A: His138, A: Glu139, A: His142, A: Y12200, A: Hoh305, A: Hoh309, A: Hoh392, A: Hoh424, conact list: Atom Atom Distance (A) Co NE2 A:Gln51 3.43 Co OE1 A:Gln51 3.79 Co CD A:Gln51 3.84 Co O A:Gly95 4.83 Co CB A:Cys96 3.47 Co SG A:Cys96 2.40 Co C A:Cys96 4.84 Co CA A:Cys96 4.10 Co N A:Leu97 4.67 Co NE2 A:His138 2.22 Co ND1 A:His138 4.36 Co CD2 A:His138 2.95 Co CE1 A:His138 3.37 Co CG A:His138 4.20 Co OE1 A:Glu139 4.42 Co OE2 A:Glu139 3.95 Co CD A:Glu139 4.53 Co NE2 A:His142 2.16 Co ND1 A:His142 4.29 Co CD2 A:His142 2.98 Co CE1 A:His142 3.26 Co CG A:His142 4.20 Co N9 A:Y12200 4.85 Co C8 A:Y12200 4.95 Co C7 A:Y12200 4.67 Co O A:Hoh305 4.46 Co O A:Hoh309 3.46 Co O A:Hoh392 3.59 Co O A:Hoh424 2.02 interactive model:
