Magnesium in the structure of A Four Location Model to Explain the Stereospecificity of Proteins. (pdb 1p8f)

The binding sites of Magnesium atom in the structure of A Four Location Model to Explain the Stereospecificity of Proteins. (pdb code 1p8f). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1p8f structure was solved by A.D.MESECAR, D.E.KOSHLAND JR., with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 24.9-1.9 Space group P43212 a (A) 103.306 b (A) 103.306 c (A) 150.004 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.2 Rfree (%) 22.5 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1p8f Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1p8f. 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: Arg129, A: Arg153, A: Asp307, A: Asp311, A: Ict601, A: Hoh802, A: Hoh837, A: Hoh976, conact list: Atom Atom Distance (A) Mg NH1 A:Arg129 4.20 Mg NH1 A:Arg153 4.76 Mg O A:Asp307 4.18 Mg CB A:Asp307 4.35 Mg OD2 A:Asp307 3.60 Mg C A:Asp307 4.67 Mg OD1 A:Asp307 2.01 Mg CG A:Asp307 3.10 Mg CA A:Asp307 4.55 Mg OD2 A:Asp311 4.51 Mg OD1 A:Asp311 3.92 Mg CG A:Asp311 4.37 Mg C6 A:Ict601 4.06 Mg O5 A:Ict601 4.30 Mg O2 A:Ict601 2.20 Mg C1 A:Ict601 2.97 Mg O1 A:Ict601 4.16 Mg C3 A:Ict601 4.17 Mg O7 A:Ict601 2.11 Mg O6 A:Ict601 4.31 Mg C2 A:Ict601 3.05 Mg O A:Hoh802 2.13 Mg O A:Hoh837 4.29 Mg O A:Hoh976 4.27 interactive model:
