Sodium in the structure of Structure Of the Side-By-Side Binding of Distamycin to Dna (pdb 378d)

The binding sites of Sodium atom in the structure of Structure Of the Side-By-Side Binding of Distamycin to Dna (pdb code 378d). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 378d structure was solved by S.N.MITRA, M.C.WAHL, M.SUNDARALINGAM, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-2.4 Space group P1211 a (A) 29.550 b (A) 42.180 c (A) 43.380 alpha (°) 90.00 beta (°) 96.56 gamma (°) 90.00 Rfactor (%) 21 Rfree (%) 28.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 378d Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 378d. 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: Da5, A: Dt6, A: Hoh75, A: Hoh76, A: Hoh77, A: Hoh78, conact list: Atom Atom Distance (A) Na O3' A:Da5 4.91 Na OP1 A:Dt6 3.91 Na P A:Dt6 4.44 Na OP2 A:Dt6 4.18 Na O A:Hoh75 2.32 Na O A:Hoh76 2.64 Na O A:Hoh77 2.16 Na O A:Hoh78 2.51 interactive model:
