Sodium in the structure of Crystal Structure of Human Frequenin (Neuronal Calcium Sensor 1) (pdb 1g8i)

The binding sites of Sodium atom in the structure of Crystal Structure of Human Frequenin (Neuronal Calcium Sensor 1) (pdb code 1g8i). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1g8i structure was solved by Y.BOURNE, J.DANNENBERG, V.POLLMANN, P.MARCHOT, O.PONGS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 38.8-1.9 Space group P1211 a (A) 53.811 b (A) 55.524 c (A) 77.705 alpha (°) 90.00 beta (°) 94.25 gamma (°) 90.00 Rfactor (%) 22 Rfree (%) 26.3 Sodium Binding Sites: Sodium binding site 1 out of 2 in 1g8i Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1g8i. 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: Lys174, A: Ala175, A: Asp176, A: Pro177, A: Hoh501, conact list: Atom Atom Distance (A) Na O A:Lys174 4.33 Na O A:Ala175 2.53 Na C A:Ala175 3.43 Na CB A:Ala175 4.89 Na CA A:Ala175 3.97 Na N A:Asp176 4.40 Na C A:Asp176 4.84 Na CA A:Asp176 4.79 Na N A:Pro177 4.46 Na CD A:Pro177 3.86 Na CG A:Pro177 3.79 Na O A:Hoh501 2.44 interactive model: Sodium binding site 2 out of 2 in 1g8i Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 2 of Sodium in the PDB 1g8i.
