Sodium in the structure of Crystallographic Evidence For Dual Coordination Around Zinc in the T3R3 Human Insulin Hexamer (pdb 1trz)

The binding sites of Sodium atom in the structure of Crystallographic Evidence For Dual Coordination Around Zinc in the T3R3 Human Insulin Hexamer (pdb code 1trz). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1trz structure was solved by E.CISZAK, G.D.SMITH, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 1.6 Space group H3 a (A) 80.638 b (A) 80.638 c (A) 37.782 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) n/a Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 1trz Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1trz. 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: D: Glu13, B: Hoh34, B: Hoh35, D: Hoh40, D: Hoh50, conact list: Atom Atom Distance (A) Na OE1 D:Glu13 2.93 Na OE2 D:Glu13 3.93 Na CD D:Glu13 3.75 Na O B:Hoh34 3.38 Na O B:Hoh35 4.83 Na O D:Hoh40 4.21 Na O D:Hoh50 2.99 interactive model:
