Sodium in the structure of Structure of Hen Egg White Lysozyme Soaked With Cu-Cyclam (pdb 1yik)

The binding sites of Sodium atom in the structure of Structure of Hen Egg White Lysozyme Soaked With Cu-Cyclam (pdb code 1yik). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1yik structure was solved by T.M.HUNTER, I.W.MCNAE, X.LIANG, J.BELLA, S.PARSONS, M.D.WALKINSHAW, P.J.SADLER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 55.0-1.8 Space group P43212 a (A) 77.906 b (A) 77.906 c (A) 37.762 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17.6 Rfree (%) 23.3 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1yik Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1yik. 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: Cys64, A: Asn65, A: Asp66, A: Thr69, A: Ser72, A: Arg73, A: Asn74, A: Cl503, A: Hoh527, A: Hoh528, A: Hoh663, conact list: Atom Atom Distance (A) Na O A:Ser60 2.27 Na CB A:Ser60 4.23 Na C A:Ser60 3.41 Na CA A:Ser60 4.04 Na O A:Arg61 4.63 Na N A:Arg61 4.49 Na C A:Arg61 4.59 Na CA A:Arg61 4.78 Na N A:Trp62 4.93 Na O A:Cys64 2.40 Na N A:Cys64 4.50 Na C A:Cys64 3.48 Na CA A:Cys64 4.62 Na N A:Asn65 4.10 Na CB A:Asn65 4.66 Na ND2 A:Asn65 4.58 Na C A:Asn65 4.68 Na CA A:Asn65 3.81 Na N A:Asp66 4.44 Na O A:Thr69 4.81 Na CB A:Thr69 4.44 Na CG2 A:Thr69 4.93 Na OG1 A:Thr69 5.00 Na O A:Ser72 4.77 Na CB A:Ser72 3.24 Na OG A:Ser72 2.42 Na C A:Ser72 4.20 Na CA A:Ser72 4.35 Na O A:Arg73 2.49 Na N A:Arg73 4.05 Na C A:Arg73 3.58 Na CA A:Arg73 4.42 Na N A:Asn74 4.49 Na CB A:Asn74 4.91 Na CA A:Asn74 4.71 Na CL A:Cl503 4.46 Na O A:Hoh527 2.25 Na O A:Hoh528 2.48 Na O A:Hoh663 4.97 interactive model:
