Sodium in the structure of Crystal Structure Analysis of the B-Dna Dodecamer Cgcgaatt(Ethenoc)Gcg (pdb 1n5c)

The binding sites of Sodium atom in the structure of Crystal Structure Analysis of the B-Dna Dodecamer Cgcgaatt(Ethenoc)Gcg (pdb code 1n5c). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1n5c structure was solved by E.FREISINGER, A.FERNANDES, A.P.GROLLMAN, C.F.KISKER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.8 Space group P3212 a (A) 26.723 b (A) 26.723 c (A) 101.544 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 16.1 Rfree (%) 21.9 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1n5c Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1n5c. 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: Dc13, A: Hoh1039, A: Hoh1042, conact list: Atom Atom Distance (A) Na N3 A:Dc13 2.29 Na C2 A:Dc13 2.72 Na C6 A:Dc13 4.85 Na N1 A:Dc13 4.12 Na C5 A:Dc13 4.66 Na O2 A:Dc13 2.39 Na C4 A:Dc13 3.44 Na N4 A:Dc13 3.82 Na O A:Hoh1039 4.78 Na O A:Hoh1042 4.80 interactive model:
