Sodium in the structure of X-Ray Structure Of First Four Repeats of Human Beta-Catenin (pdb 3sla)

The binding sites of Sodium atom in the structure of X-Ray Structure Of First Four Repeats of Human Beta-Catenin (pdb code 3sla). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3sla structure was solved by D.GUPTA, M.BIENZ, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 40.7-2.5 Space group P41212 a (A) 90.790 b (A) 90.790 c (A) 364.340 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 21.8 Rfree (%) 27.7 Sodium Binding Sites: Sodium binding site 1 out of 2 in 3sla Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3sla. 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: E: His219, E: His223, E: Thr257, E: Asn261, E: Na2, conact list: Atom Atom Distance (A) Na NE2 E:His219 4.64 Na ND1 E:His219 4.65 Na CE1 E:His219 3.83 Na NE2 E:His223 4.46 Na ND1 E:His223 3.57 Na CE1 E:His223 3.22 Na CG E:His223 4.94 Na CB E:Thr257 4.85 Na CG2 E:Thr257 4.53 Na ND2 E:Asn261 3.20 Na OD1 E:Asn261 3.96 Na CG E:Asn261 4.02 Na NA E:Na2 3.99 interactive model: Sodium binding site 2 out of 2 in 3sla Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 2 of Sodium in the PDB 3sla.
