Arsenic in the structure of The Structure of the B-Dna Decamer C-C-A-A-C-I-T-T-G-G: Monoclinic Form (pdb 1d61)

The binding sites of Arsenic atom in the structure of The Structure of the B-Dna Decamer C-C-A-A-C-I-T-T-G-G: Monoclinic Form (pdb code 1d61). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 1d61 structure was solved by A.LIPANOV, M.L.KOPKA, M.KACZOR-GRZESKOWIAK, J.QUINTANA, R.E.DICKERSON, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 8.0-1.3 Space group C121 a (A) 31.870 b (A) 25.690 c (A) 34.210 alpha (°) 90.00 beta (°) 114.10 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 1d61 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 1d61. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Arsenic atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: Dc1, A: Dc2, A: Cac11, A: Hoh20, A: Hoh34, conact list: Atom Atom Distance (A) As O2 A:Dc1 4.92 As O4' A:Dc2 4.35 As C5' A:Dc2 4.35 As C4' A:Dc2 4.31 As O1 A:Cac11 2.63 As AS A:Cac11 0.00 As O A:Hoh20 4.70 As O A:Hoh34 2.33 interactive model:
