Sodium in the structure of Product Bound Structure of Exonuclease I At 1.5 Angstrom Resolution (pdb 2qxf)

The binding sites of Sodium atom in the structure of Product Bound Structure of Exonuclease I At 1.5 Angstrom Resolution (pdb code 2qxf). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2qxf structure was solved by R.D.BUSAM, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 26.3-1.5 Space group P212121 a (A) 52.630 b (A) 91.849 c (A) 102.752 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.9 Rfree (%) 22.4 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2qxf Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2qxf. 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: Asp15, A: Glu17, A: Gln30, A: Asp182, A: Ala183, A: Asp186, A: Mg2000, A: Hoh3078, A: Hoh3105, A: Hoh3106, A: Hoh3107, A: Hoh3108, A: Hoh3109, A: Hoh3110, A: Hoh3111, A: Hoh3125, A: Hoh3173, A: Hoh3251, A: Hoh3255, conact list: Atom Atom Distance (A) Na OD2 A:Asp15 4.01 Na OE1 A:Glu17 4.56 Na OE2 A:Glu17 2.41 Na CD A:Glu17 3.46 Na CG A:Glu17 3.77 Na OE1 A:Gln30 4.51 Na O A:Asp182 4.75 Na O A:Ala183 3.85 Na C A:Ala183 4.71 Na N A:Asp186 4.60 Na CB A:Asp186 3.97 Na OD2 A:Asp186 2.39 Na OD1 A:Asp186 4.33 Na CG A:Asp186 3.40 Na CA A:Asp186 4.94 Na MG A:Mg2000 3.14 Na O A:Hoh3078 4.99 Na O A:Hoh3105 4.10 Na O A:Hoh3106 4.25 Na O A:Hoh3107 2.33 Na O A:Hoh3108 3.83 Na O A:Hoh3109 2.26 Na O A:Hoh3110 3.86 Na O A:Hoh3111 2.63 Na O A:Hoh3125 2.28 Na O A:Hoh3173 4.46 Na O A:Hoh3251 4.53 Na O A:Hoh3255 4.81 interactive model:
