Sodium in the structure of Crystal Structure of Mutant Human Lysozyme Substituted At the Surface Positions (pdb 1gbz)

The binding sites of Sodium atom in the structure of Crystal Structure of Mutant Human Lysozyme Substituted At the Surface Positions (pdb code 1gbz). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1gbz structure was solved by J.FUNAHASHI, K.TAKANO, Y.YAMAGATA, K.YUTANI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-1.8 Space group P212121 a (A) 56.510 b (A) 60.280 c (A) 32.400 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17.8 Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 1gbz Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1gbz. 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: Gly22, A: Ile23, A: Ser24, A: Asn27, A: Hoh133, A: Hoh146, conact list: Atom Atom Distance (A) Na O A:Gly22 2.92 Na C A:Gly22 4.02 Na N A:Ile23 4.45 Na C A:Ile23 3.98 Na CA A:Ile23 3.89 Na N A:Ser24 3.16 Na CB A:Ser24 3.69 Na OG A:Ser24 3.55 Na CA A:Ser24 4.01 Na ND2 A:Asn27 3.48 Na CG A:Asn27 4.56 Na O A:Hoh133 3.24 Na O A:Hoh146 4.73 interactive model:
