Sodium in the structure of Phase Transition of Monoclinic Lysozyme Crystal Soaked in A 10% Nacl Solution (pdb 2z18)

The binding sites of Sodium atom in the structure of Phase Transition of Monoclinic Lysozyme Crystal Soaked in A 10% Nacl Solution (pdb code 2z18). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2z18 structure was solved by K.HARATA, T.AKIBA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 25.0-1.1 Space group P1211 a (A) 26.622 b (A) 60.588 c (A) 31.223 alpha (°) 90.00 beta (°) 111.44 gamma (°) 90.00 Rfactor (%) 15.6 Rfree (%) 17.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2z18 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2z18. 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: Ser60, A: Arg61, A: Trp62, A: Trp63, A: Cys64, A: Asn65, A: Asp66, A: Thr69, A: Ser72, A: Arg73, A: Asn74, A: Cl135, A: Hoh141, A: Hoh142, A: Hoh158, A: Hoh214, conact list: Atom Atom Distance (A) Na O A:Ser60 2.37 Na CB A:Ser60 4.43 Na C A:Ser60 3.53 Na CA A:Ser60 4.19 Na O A:Arg61 4.49 Na N A:Arg61 4.58 Na C A:Arg61 4.45 Na CA A:Arg61 4.73 Na N A:Trp62 4.77 Na N A:Trp63 4.95 Na O A:Cys64 2.34 Na N A:Cys64 4.36 Na C A:Cys64 3.46 Na CA A:Cys64 4.59 Na N A:Asn65 4.11 Na CB A:Asn65 4.92 Na C A:Asn65 4.97 Na OD1 A:Asn65 4.73 Na CA A:Asn65 4.00 Na N A:Asp66 4.87 Na OG1 A:Thr69 4.67 Na O A:Ser72 4.94 Na CB A:Ser72 3.42 Na OG A:Ser72 2.56 Na C A:Ser72 4.27 Na CA A:Ser72 4.48 Na O A:Arg73 2.42 Na N A:Arg73 3.92 Na C A:Arg73 3.45 Na CA A:Arg73 4.28 Na N A:Asn74 4.33 Na CB A:Asn74 4.72 Na CA A:Asn74 4.57 Na CL A:Cl135 4.39 Na O A:Hoh141 2.54 Na O A:Hoh142 2.37 Na O A:Hoh158 4.94 Na O A:Hoh214 4.54 interactive model:
