Sodium in the structure of Crystal Structure of Human Lysozyme From Urine (pdb 2zil)

The binding sites of Sodium atom in the structure of Crystal Structure of Human Lysozyme From Urine (pdb code 2zil). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2zil structure was solved by T.TAMADA, R.KUROKI, T.KOSHIBA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 41.5-1.8 Space group P212121 a (A) 56.700 b (A) 61.000 c (A) 34.000 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17 Rfree (%) 22.7 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2zil Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2zil. 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: Ser61, A: Arg62, A: Tyr63, A: Trp64, A: Cys65, A: Asn66, A: Asp67, A: Ala73, A: Val74, A: Asn75, A: Hoh147, A: Hoh152, A: Hoh153, conact list: Atom Atom Distance (A) Na O A:Ser61 2.28 Na CB A:Ser61 4.60 Na C A:Ser61 3.44 Na CA A:Ser61 4.20 Na O A:Arg62 4.15 Na N A:Arg62 4.44 Na C A:Arg62 4.19 Na CA A:Arg62 4.52 Na N A:Tyr63 4.56 Na C A:Tyr63 4.86 Na N A:Trp64 4.68 Na C A:Trp64 4.95 Na O A:Cys65 2.17 Na N A:Cys65 4.13 Na C A:Cys65 3.18 Na CA A:Cys65 4.28 Na N A:Asn66 3.79 Na CB A:Asn66 4.49 Na C A:Asn66 4.72 Na OD1 A:Asn66 4.39 Na CG A:Asn66 4.95 Na CA A:Asn66 3.67 Na N A:Asp67 4.66 Na O A:Ala73 4.88 Na C A:Ala73 4.18 Na CB A:Ala73 3.39 Na CA A:Ala73 4.35 Na O A:Val74 2.30 Na N A:Val74 3.89 Na C A:Val74 3.31 Na CA A:Val74 4.15 Na N A:Asn75 4.16 Na CB A:Asn75 4.43 Na CA A:Asn75 4.25 Na O A:Hoh147 2.39 Na O A:Hoh152 4.66 Na O A:Hoh153 2.70 interactive model:
