Sodium in the structure of The Crystal Structure Of The Tolb Box Of Colicin A In Complex With Tolb Reveals Important Differences in The Recruitment of the Common Tolb Translocation Portal Used By Group A Colicins (pdb 3iax)

The binding sites of Sodium atom in the structure of The Crystal Structure Of The Tolb Box Of Colicin A In Complex With Tolb Reveals Important Differences in The Recruitment of the Common Tolb Translocation Portal Used By Group A Colicins (pdb code 3iax). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3iax structure was solved by C.LI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-2.6 Space group P1211 a (A) 61.955 b (A) 40.174 c (A) 80.868 alpha (°) 90.00 beta (°) 97.18 gamma (°) 90.00 Rfactor (%) 19 Rfree (%) 25.7 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3iax Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3iax. 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: Arg142, A: His146, A: Asp186, A: Asp188, A: Tyr190, A: Asn191, A: Hoh445, conact list: Atom Atom Distance (A) Na CB A:Arg142 4.07 Na CD A:Arg142 3.46 Na CZ A:Arg142 3.65 Na CG A:Arg142 4.26 Na NE A:Arg142 2.72 Na NH2 A:Arg142 3.75 Na NH1 A:Arg142 4.84 Na NE2 A:His146 2.79 Na ND1 A:His146 4.90 Na CD2 A:His146 3.63 Na CE1 A:His146 3.81 Na CG A:His146 4.85 Na CB A:Asp186 3.50 Na OD2 A:Asp186 2.61 Na OD1 A:Asp186 4.59 Na CG A:Asp186 3.45 Na CB A:Asp188 4.76 Na OD2 A:Asp188 3.13 Na OD1 A:Asp188 2.61 Na CG A:Asp188 3.26 Na O A:Tyr190 4.51 Na N A:Tyr190 4.55 Na CB A:Tyr190 3.51 Na CD2 A:Tyr190 4.37 Na C A:Tyr190 4.68 Na CG A:Tyr190 4.18 Na CA A:Tyr190 4.45 Na ND2 A:Asn191 4.38 Na O A:Hoh445 4.74 interactive model:
