Magnesium in the structure of Structural Studies on Nucleic Acids (pdb 270d)

The binding sites of Magnesium atom in the structure of Structural Studies on Nucleic Acids (pdb code 270d). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 270d structure was solved by B.L.PARTRIDGE, S.A.SALISBURY, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 2.0 Space group P212121 a (A) 24.828 b (A) 40.323 c (A) 65.563 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 270d Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 270d. 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: Dc1, A: Dg2, A: Dc3, B: Dg22, A: Hoh65, A: Hoh69, A: Hoh96, A: Hoh143, A: Hoh146, A: Hoh147, A: Hoh148, B: Hoh38, B: Hoh44, B: Hoh144, B: Hoh145, conact list: Atom Atom Distance (A) Mg C6 A:Dc1 4.65 Mg C5 A:Dc1 4.26 Mg N7 A:Dg2 4.27 Mg O6 A:Dg2 4.34 Mg N4 A:Dc3 4.85 Mg O6 B:Dg22 4.15 Mg O A:Hoh65 4.45 Mg O A:Hoh69 3.86 Mg O A:Hoh96 4.10 Mg O A:Hoh143 2.04 Mg O A:Hoh146 1.98 Mg O A:Hoh147 1.97 Mg O A:Hoh148 2.01 Mg O B:Hoh38 4.19 Mg O B:Hoh44 4.18 Mg O B:Hoh144 1.90 Mg O B:Hoh145 2.05 interactive model:
