Sodium in the structure of Structure Of Human Insulin Cocrystallized With Arg-12 Peptide in Presence of Urea (pdb 2omh)

The binding sites of Sodium atom in the structure of Structure Of Human Insulin Cocrystallized With Arg-12 Peptide in Presence of Urea (pdb code 2omh). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2omh structure was solved by M.NORRMAN, G.SCHLUCKEBIER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 14.9-1.4 Space group P43212 a (A) 61.360 b (A) 61.360 c (A) 85.600 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20 Rfree (%) 22.3 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2omh Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2omh. 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: Glu17, A: Asn18, A: Tyr19, A: Cys20, A: Asn21, A: Hoh607, A: Hoh612, A: Hoh619, A: Hoh623, A: Hoh626, A: Hoh629, A: Hoh630, B: Hoh311, conact list: Atom Atom Distance (A) Na O A:Glu17 4.30 Na O A:Asn18 2.47 Na C A:Asn18 3.49 Na OD1 A:Asn18 4.87 Na CA A:Asn18 4.45 Na O A:Tyr19 4.65 Na N A:Tyr19 4.22 Na C A:Tyr19 4.10 Na CA A:Tyr19 4.27 Na O A:Cys20 2.41 Na N A:Cys20 3.91 Na CB A:Cys20 4.99 Na C A:Cys20 3.61 Na CA A:Cys20 4.35 Na N A:Asn21 4.63 Na C A:Asn21 4.65 Na CA A:Asn21 4.77 Na OXT A:Asn21 4.61 Na O A:Hoh607 4.55 Na O A:Hoh612 2.60 Na O A:Hoh619 4.75 Na O A:Hoh623 4.68 Na O A:Hoh626 2.11 Na O A:Hoh629 2.27 Na O A:Hoh630 2.77 Na O B:Hoh311 5.00 interactive model:
