Sodium in the structure of Structure Of MG2+ Bound N-Terminal Domain Of Calmodulin in the Presence of ZN2+ (pdb 3ucy)

The binding sites of Sodium atom in the structure of Structure Of MG2+ Bound N-Terminal Domain Of Calmodulin in the Presence of ZN2+ (pdb code 3ucy). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3ucy structure was solved by F.T.SENGUEN, Z.GRABAREK, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 35.7-1.8 Space group P43212 a (A) 35.298 b (A) 35.298 c (A) 142.937 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.1 Rfree (%) 22.8 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3ucy Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3ucy. 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: Asp20, A: Lys21, A: Asp22, A: Gly23, A: Asp24, A: Gly25, A: Thr26, A: Ile27, A: Zn102, A: Cac200, A: Hoh301, A: Hoh341, conact list: Atom Atom Distance (A) Na O A:Asp20 4.89 Na CB A:Asp20 4.35 Na OD2 A:Asp20 4.45 Na C A:Asp20 4.33 Na OD1 A:Asp20 2.43 Na CG A:Asp20 3.56 Na CA A:Asp20 4.08 Na N A:Lys21 4.46 Na N A:Asp22 4.24 Na CB A:Asp22 4.63 Na OD2 A:Asp22 3.91 Na C A:Asp22 4.82 Na OD1 A:Asp22 2.40 Na CG A:Asp22 3.44 Na CA A:Asp22 4.72 Na N A:Gly23 4.59 Na N A:Asp24 4.20 Na CB A:Asp24 4.64 Na OD2 A:Asp24 3.84 Na C A:Asp24 4.83 Na OD1 A:Asp24 2.55 Na CG A:Asp24 3.46 Na CA A:Asp24 4.74 Na N A:Gly25 4.70 Na O A:Thr26 2.33 Na N A:Thr26 3.89 Na CB A:Thr26 4.31 Na OG1 A:Thr26 3.31 Na C A:Thr26 3.43 Na CA A:Thr26 4.07 Na N A:Ile27 4.50 Na CA A:Ile27 4.83 Na ZN A:Zn102 3.43 Na O1 A:Cac200 4.97 Na O2 A:Cac200 2.39 Na AS A:Cac200 3.78 Na C2 A:Cac200 4.09 Na C1 A:Cac200 4.97 Na O A:Hoh301 2.34 Na O A:Hoh341 4.60 interactive model:
