Sodium in the structure of Na Substituted E. Coli Aminopeptidase P (pdb 2bhc)

The binding sites of Sodium atom in the structure of Na Substituted E. Coli Aminopeptidase P (pdb code 2bhc). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2bhc structure was solved by S.C.GRAHAM, C.S.BOND, H.C.FREEMAN, J.M.GUSS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 60.2-2.4 Space group I4122 a (A) 138.783 b (A) 138.783 c (A) 231.012 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17.6 Rfree (%) 20.2 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2bhc Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2bhc. 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: Asp271, A: His354, A: His361, A: Thr381, A: Glu383, A: Glu406, A: Hoh2030, A: Hoh2137, conact list: Atom Atom Distance (A) Na CB A:Asp271 4.70 Na OD2 A:Asp271 2.51 Na OD1 A:Asp271 3.45 Na CG A:Asp271 3.32 Na NE2 A:His354 2.50 Na ND1 A:His354 4.57 Na CD2 A:His354 3.41 Na CE1 A:His354 3.47 Na CG A:His354 4.57 Na NE2 A:His361 4.71 Na CD2 A:His361 4.96 Na CB A:Thr381 4.29 Na CG2 A:Thr381 4.11 Na OG1 A:Thr381 4.05 Na OE1 A:Glu383 3.28 Na OE2 A:Glu383 2.59 Na CD A:Glu383 3.23 Na CG A:Glu383 4.55 Na OE1 A:Glu406 3.38 Na OE2 A:Glu406 2.29 Na CD A:Glu406 3.19 Na CG A:Glu406 4.57 Na O A:Hoh2030 2.62 Na O A:Hoh2137 2.70 interactive model:
