Sodium in the structure of Crystal Structure Of The Calcium Pump With Amppcp in the Absence of Calcium (pdb 2dqs)

The binding sites of Sodium atom in the structure of Crystal Structure Of The Calcium Pump With Amppcp in the Absence of Calcium (pdb code 2dqs). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2dqs structure was solved by C.TOYOSHIMA, Y.NORIMATSU, J.TSUEDA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 15.0-2.5 Space group P41212 a (A) 71.421 b (A) 71.421 c (A) 589.756 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 23.4 Rfree (%) 27.8 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2dqs Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2dqs. 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: Gln244, A: Leu711, A: Lys712, A: Lys713, A: Ala714, A: Glu715, A: Ile716, A: Gly717, A: Ala730, A: Glu732, A: Hoh2036, conact list: Atom Atom Distance (A) Na NE2 A:Gln244 3.59 Na OE1 A:Gln244 2.31 Na CD A:Gln244 3.27 Na CG A:Gln244 4.65 Na O A:Leu711 2.71 Na C A:Leu711 3.81 Na O A:Lys712 2.43 Na N A:Lys712 4.24 Na C A:Lys712 3.15 Na CA A:Lys712 3.66 Na O A:Lys713 4.35 Na N A:Lys713 4.09 Na C A:Lys713 4.05 Na CA A:Lys713 4.53 Na O A:Ala714 2.22 Na N A:Ala714 3.97 Na C A:Ala714 3.43 Na CB A:Ala714 4.80 Na CA A:Ala714 4.26 Na O A:Glu715 4.04 Na N A:Glu715 4.41 Na C A:Glu715 4.11 Na CA A:Glu715 4.52 Na N A:Ile716 4.48 Na C A:Ile716 4.72 Na CA A:Ile716 4.81 Na N A:Gly717 3.91 Na CA A:Gly717 4.51 Na O A:Ala730 4.75 Na OE1 A:Glu732 2.35 Na OE2 A:Glu732 3.48 Na CD A:Glu732 3.14 Na CG A:Glu732 4.35 Na O A:Hoh2036 2.68 interactive model:
