Sodium in the structure of Structure of the Thaumatin-Like Xylanase Inhibitor Tlxi (pdb 3g7m)

The binding sites of Sodium atom in the structure of Structure of the Thaumatin-Like Xylanase Inhibitor Tlxi (pdb code 3g7m). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3g7m structure was solved by E.VANDERMARLIERE, C.M.COURTIN, W.LAMMENS, J.SCHOEPE, S.V.STRELKOV, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 19.2-2.9 Space group P321 a (A) 104.019 b (A) 104.019 c (A) 30.047 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 22.8 Rfree (%) 28.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3g7m Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3g7m. 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: Arg51, A: Phe56, A: Gly71, A: Ser72, A: Leu74, conact list: Atom Atom Distance (A) Na CZ A:Arg51 4.35 Na NH2 A:Arg51 3.81 Na NH1 A:Arg51 3.91 Na CE2 A:Phe56 4.64 Na CZ A:Phe56 4.87 Na O A:Gly71 4.87 Na O A:Ser72 3.62 Na C A:Ser72 4.37 Na CA A:Ser72 4.23 Na CD1 A:Leu74 4.07 Na CG A:Leu74 4.60 interactive model:
