Sodium in the structure of Apo Crystal Structure of Nuclease A From Anabaena Sp. (pdb 1zm8)

The binding sites of Sodium atom in the structure of Apo Crystal Structure of Nuclease A From Anabaena Sp. (pdb code 1zm8). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1zm8 structure was solved by M.GHOSH, G.MEISS, A.PINGOUD, R.E.LONDON, L.C.PEDERSEN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.9-1.9 Space group P212121 a (A) 46.690 b (A) 66.682 c (A) 81.730 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 21.2 Rfree (%) 25.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1zm8 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1zm8. 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: Asp153, A: Asn157, A: Glu233, A: Leu234, A: Asn235, A: Asn236, conact list: Atom Atom Distance (A) Na CB A:Asp153 4.63 Na OD2 A:Asp153 2.33 Na OD1 A:Asp153 3.36 Na CG A:Asp153 3.20 Na CB A:Asn157 4.95 Na ND2 A:Asn157 4.34 Na C A:Glu233 4.70 Na O A:Leu234 2.06 Na N A:Leu234 3.58 Na CB A:Leu234 4.46 Na C A:Leu234 3.17 Na CA A:Leu234 3.88 Na O A:Asn235 4.84 Na N A:Asn235 4.22 Na C A:Asn235 4.25 Na CA A:Asn235 4.49 Na N A:Asn236 3.97 Na CB A:Asn236 4.51 Na ND2 A:Asn236 4.23 Na OD1 A:Asn236 2.26 Na CG A:Asn236 3.46 Na CA A:Asn236 4.43 interactive model:
