Sodium in the structure of Crystal Structure of Thermitase At 1.4 Angstroms Resolution (pdb 1thm)

The binding sites of Sodium atom in the structure of Crystal Structure of Thermitase At 1.4 Angstroms Resolution (pdb code 1thm). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1thm structure was solved by A.V.TEPLYAKOV, I.P.KURANOVA, E.H.HARUTYUNYAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 7.0-1.4 Space group P212121 a (A) 72.950 b (A) 64.050 c (A) 47.550 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 1 in 1thm Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1thm. 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: Ala173, A: Tyr174, A: Tyr175, A: Ser176, A: Ala178, A: Ile179, A: Ala180, A: Trp199, A: Asp201, A: Arg249, A: Hoh335, A: Hoh364, A: Hoh420, conact list: Atom Atom Distance (A) Na O A:Ala173 2.83 Na C A:Ala173 4.06 Na O A:Tyr174 4.14 Na N A:Tyr174 4.77 Na C A:Tyr174 4.13 Na CA A:Tyr174 4.51 Na O A:Tyr175 2.96 Na N A:Tyr175 4.48 Na C A:Tyr175 3.96 Na CA A:Tyr175 4.88 Na O A:Ser176 4.43 Na N A:Ser176 4.68 Na C A:Ser176 4.67 Na CA A:Ser176 4.60 Na O A:Ala178 2.80 Na N A:Ala178 4.61 Na C A:Ala178 3.84 Na CB A:Ala178 4.64 Na CA A:Ala178 4.65 Na N A:Ile179 4.70 Na C A:Ile179 4.75 Na CA A:Ile179 4.73 Na N A:Ala180 4.10 Na CB A:Ala180 4.10 Na CA A:Ala180 4.74 Na O A:Trp199 4.10 Na OD2 A:Asp201 2.98 Na OD1 A:Asp201 4.25 Na CG A:Asp201 4.03 Na NH2 A:Arg249 4.44 Na O A:Hoh335 2.95 Na O A:Hoh364 4.44 Na O A:Hoh420 2.90 interactive model:
