Sodium in the structure of Non-Covalent Complex Between UBC9 and SUMO1 (pdb 2uyz)

The binding sites of Sodium atom in the structure of Non-Covalent Complex Between UBC9 and SUMO1 (pdb code 2uyz). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2uyz structure was solved by P.KNIPSCHEER, W.J.VAN DIJK, J.V.OLSEN, M.MANN, T.K.SIXMA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 50.0-1.4 Space group P1211 a (A) 49.481 b (A) 35.030 c (A) 72.915 alpha (°) 90.00 beta (°) 93.41 gamma (°) 90.00 Rfactor (%) 14.1 Rfree (%) 17.8 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2uyz Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2uyz. 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: Tyr87, A: Ser93, A: Glu98, A: Asp127, A: Hoh2140, A: Hoh2142, A: Hoh2147, A: Hoh2148, A: Hoh2154, A: Hoh2155, A: Hoh2156, A: Hoh2157, A: Hoh2208, conact list: Atom Atom Distance (A) Na CE2 A:Tyr87 3.49 Na CD2 A:Tyr87 4.81 Na CZ A:Tyr87 3.60 Na CE1 A:Tyr87 4.96 Na OH A:Tyr87 2.80 Na CB A:Ser93 3.51 Na OG A:Ser93 2.83 Na C A:Ser93 5.00 Na CA A:Ser93 4.03 Na OE1 A:Glu98 4.93 Na OE2 A:Glu98 3.42 Na CD A:Glu98 4.28 Na OD2 A:Asp127 4.69 Na O A:Hoh2140 2.15 Na O A:Hoh2142 4.88 Na O A:Hoh2147 3.41 Na O A:Hoh2148 4.18 Na O A:Hoh2154 2.28 Na O A:Hoh2155 3.59 Na O A:Hoh2156 4.66 Na O A:Hoh2157 2.75 Na O A:Hoh2208 3.52 interactive model:
