Sodium in the structure of Structure of Hen Egg-White Lysozyme Determined From Crystals Grown in pH 7.5 (pdb 2hub)

The binding sites of Sodium atom in the structure of Structure of Hen Egg-White Lysozyme Determined From Crystals Grown in pH 7.5 (pdb code 2hub). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2hub structure was solved by F.FROLOW, S.LAGZIEL-SIMIS, N.COHEN-HADAR, Y.WINE, A.FREEMAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 54.3-1.2 Space group P43212 a (A) 76.861 b (A) 76.861 c (A) 35.867 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 13.7 Rfree (%) 17.3 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2hub Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2hub. 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: Arg45, A: Gly49, A: Ser50, A: Thr51, A: Tyr53, A: Ser60, A: Asp66, A: Arg68, A: Thr69, conact list: Atom Atom Distance (A) Na CD A:Arg45 4.39 Na CZ A:Arg45 4.32 Na NE A:Arg45 4.60 Na NH1 A:Arg45 3.69 Na O A:Gly49 2.98 Na C A:Gly49 3.98 Na O A:Ser50 3.97 Na N A:Ser50 4.33 Na CB A:Ser50 4.95 Na C A:Ser50 3.45 Na CA A:Ser50 3.69 Na N A:Thr51 3.40 Na CB A:Thr51 3.48 Na CG2 A:Thr51 4.79 Na OG1 A:Thr51 2.72 Na CA A:Thr51 4.05 Na OH A:Tyr53 4.36 Na CB A:Ser60 4.74 Na OG A:Ser60 3.76 Na OD2 A:Asp66 2.72 Na OD1 A:Asp66 3.92 Na CG A:Asp66 3.70 Na O A:Arg68 4.46 Na CB A:Arg68 4.81 Na CD A:Arg68 3.77 Na CZ A:Arg68 3.80 Na C A:Arg68 4.58 Na CG A:Arg68 3.51 Na NE A:Arg68 2.93 Na NH2 A:Arg68 3.83 Na N A:Thr69 4.72 Na CB A:Thr69 4.40 Na CG2 A:Thr69 4.90 Na OG1 A:Thr69 3.13 Na CA A:Thr69 4.67 interactive model:
