Magnesium in the structure of Crystal Structure of 3-Keto-L-Gulonate 6-Phosphate Decarboxylase (pdb 1kv8)

The binding sites of Magnesium atom in the structure of Crystal Structure of 3-Keto-L-Gulonate 6-Phosphate Decarboxylase (pdb code 1kv8). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1kv8 structure was solved by E.WISE, W.S.YEW, P.C.BABBITT, J.A.GERLT, I.RAYMENT, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 500.0-1.6 Space group C121 a (A) 123.470 b (A) 41.631 c (A) 90.633 alpha (°) 90.00 beta (°) 97.20 gamma (°) 90.00 Rfactor (%) 18.2 Rfree (%) 19.9 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1kv8 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1kv8. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Magnesium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Ala9, A: Asp11, A: Glu33, A: Gly35, A: Thr36, A: Asp62, A: Lys64, A: Glu112, A: His136, A: Hoh520, A: Hoh535, A: Hoh537, A: Hoh552, A: Hoh633, A: Hoh634, A: Hoh645, B: Hoh625, conact list: Atom Atom Distance (A) Mg CB A:Ala9 4.64 Mg OD2 A:Asp11 4.29 Mg OD1 A:Asp11 4.14 Mg CG A:Asp11 4.65 Mg OE1 A:Glu33 3.82 Mg OE2 A:Glu33 2.44 Mg CD A:Glu33 3.44 Mg CG A:Glu33 4.69 Mg CA A:Gly35 4.42 Mg N A:Thr36 4.52 Mg OG1 A:Thr36 4.67 Mg CB A:Asp62 4.31 Mg OD2 A:Asp62 2.42 Mg OD1 A:Asp62 4.55 Mg CG A:Asp62 3.61 Mg NZ A:Lys64 3.85 Mg OE2 A:Glu112 4.78 Mg ND1 A:His136 4.92 Mg CE1 A:His136 4.24 Mg O A:Hoh520 2.20 Mg O A:Hoh535 2.76 Mg O A:Hoh537 3.83 Mg O A:Hoh552 4.06 Mg O A:Hoh633 4.75 Mg O A:Hoh634 2.58 Mg O A:Hoh645 2.31 Mg O B:Hoh625 4.43 interactive model:
