Sodium in the structure of Crystal Structure of Poliovirus Polymerase Complexed With Ctp and MG2+ (pdb 2im0)

The binding sites of Sodium atom in the structure of Crystal Structure of Poliovirus Polymerase Complexed With Ctp and MG2+ (pdb code 2im0). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2im0 structure was solved by A.A.THOMPSON, O.B.PEERSEN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 25.8-2.2 Space group P65 a (A) 127.695 b (A) 127.695 c (A) 113.034 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 23.7 Rfree (%) 26 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2im0 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2im0. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Sodium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Tyr267, A: Leu268, A: Asn269, A: His270, A: Ser271, A: His273, A: Val282, A: Lys283, A: Gly284, A: Gly285, A: Met286, A: Pro287, A: Hoh673, A: Hoh681, conact list: Atom Atom Distance (A) Na O A:Tyr267 4.93 Na O A:Leu268 2.57 Na C A:Leu268 3.69 Na CA A:Leu268 4.91 Na O A:Asn269 2.85 Na N A:Asn269 4.25 Na C A:Asn269 3.50 Na CA A:Asn269 3.94 Na N A:His270 4.43 Na C A:His270 4.76 Na CA A:His270 4.81 Na N A:Ser271 3.98 Na CB A:Ser271 3.75 Na OG A:Ser271 2.86 Na CA A:Ser271 4.51 Na NE2 A:His273 4.70 Na O A:Val282 3.90 Na CB A:Val282 4.27 Na C A:Val282 4.50 Na CG1 A:Val282 4.14 Na C A:Lys283 4.91 Na O A:Gly284 2.53 Na N A:Gly284 4.15 Na C A:Gly284 3.32 Na CA A:Gly284 4.24 Na O A:Gly285 2.58 Na N A:Gly285 3.98 Na C A:Gly285 3.59 Na CA A:Gly285 3.99 Na N A:Met286 4.77 Na N A:Pro287 4.98 Na CD A:Pro287 4.40 Na CG A:Pro287 4.29 Na O A:Hoh673 4.99 Na O A:Hoh681 2.52 interactive model:
