Magnesium in the structure of The Crystal Structure of the Molybdenum Storage Protein From Azotobacter Vinelandii Loaded With Polyoxotungstates (Wsto) (pdb 2ogx)

The binding sites of Magnesium atom in the structure of The Crystal Structure of the Molybdenum Storage Protein From Azotobacter Vinelandii Loaded With Polyoxotungstates (Wsto) (pdb code 2ogx). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 2ogx structure was solved by J.SCHEMBERG, E.WARKENTIN, U.ERMLER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 10.0-1.6 Space group P6322 a (A) 114.400 b (A) 114.400 c (A) 233.700 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 17.3 Rfree (%) 19.6 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 2ogx Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 2ogx. 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: Lys45, A: Asp171, A: Glu190, A: Pro227, A: Val228, A: Atp281, A: Hoh3031, A: Hoh3054, A: Hoh3438, B: Hoh3090, conact list: Atom Atom Distance (A) Mg NZ A:Lys45 3.97 Mg OD2 A:Asp171 3.85 Mg OD1 A:Asp171 4.18 Mg CG A:Asp171 4.44 Mg OE1 A:Glu190 3.70 Mg OE1 A:Glu190 3.26 Mg OE2 A:Glu190 2.51 Mg OE2 A:Glu190 2.10 Mg CD A:Glu190 3.15 Mg CD A:Glu190 2.86 Mg CG A:Glu190 4.00 Mg O A:Pro227 2.12 Mg CB A:Pro227 4.39 Mg C A:Pro227 3.27 Mg CA A:Pro227 4.05 Mg N A:Val228 4.25 Mg CG1 A:Val228 4.97 Mg CA A:Val228 4.36 Mg PG A:Atp281 4.75 Mg O3B A:Atp281 4.31 Mg PA A:Atp281 3.32 Mg O5' A:Atp281 4.32 Mg O2B A:Atp281 2.03 Mg O3A A:Atp281 3.59 Mg O3G A:Atp281 4.20 Mg O2A A:Atp281 2.09 Mg O1B A:Atp281 4.33 Mg PB A:Atp281 3.31 Mg C5' A:Atp281 4.13 Mg O1G A:Atp281 4.93 Mg O1A A:Atp281 4.31 Mg O A:Hoh3031 4.93 Mg O A:Hoh3054 4.38 Mg O A:Hoh3438 2.04 Mg O B:Hoh3090 3.92 interactive model:
