Arsenic in the structure of Crystal Structure Of the Rna Triphosphatase Domain of Mouse Mrna Capping Enzyme (pdb 1i9s)

The binding sites of Arsenic atom in the structure of Crystal Structure Of the Rna Triphosphatase Domain of Mouse Mrna Capping Enzyme (pdb code 1i9s). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 1i9s structure was solved by A.CHANGELA, C.K.HO, A.MARTINS, S.SHUMAN, A.MONDRAGON, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 27.0-1.6 Space group C2221 a (A) 62.228 b (A) 98.856 c (A) 71.818 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.4 Rfree (%) 22.5 Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 1i9s Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 1i9s. 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: Arg9, A: Tyr165, A: Trp192, A: Cys193, A: Cac400, conact list: Atom Atom Distance (A) As CD A:Arg9 4.46 As CZ A:Arg9 4.53 As NE A:Arg9 4.80 As NH1 A:Arg9 3.61 As CE2 A:Tyr165 4.61 As CZ A:Tyr165 4.64 As OH A:Tyr165 4.56 As CE3 A:Trp192 4.49 As CZ3 A:Trp192 3.76 As CZ2 A:Trp192 4.69 As CH2 A:Trp192 3.88 As O A:Cys193 4.58 As N A:Cys193 4.68 As CB A:Cys193 3.22 As SG A:Cys193 2.41 As C A:Cys193 4.66 As CA A:Cys193 3.72 As AS A:Cac400 0.00 As C2 A:Cac400 2.06 As C1 A:Cac400 2.12 interactive model:
