Arsenic in the structure of Arsenate Reductase R60K Mutant +0.4M Arsenate From E. Coli (pdb 1sk1)

The binding sites of Arsenic atom in the structure of Arsenate Reductase R60K Mutant +0.4M Arsenate From E. Coli (pdb code 1sk1). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 1sk1 structure was solved by S.DEMEL, B.F.EDWARDS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.6 Space group P6122 a (A) 86.680 b (A) 86.680 c (A) 116.060 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 17.5 Rfree (%) 21.2 Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 1sk1 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 1sk1. 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: Csr12, A: Gly13, A: Thr14, A: Arg94, A: Arg107, A: So4201, A: Hoh1281, A: Hoh1303, conact list: Atom Atom Distance (A) As O A:Csr12 4.62 As O2 A:Csr12 1.68 As N A:Csr12 4.81 As CB A:Csr12 2.99 As CB A:Csr12 3.01 As SG A:Csr12 1.87 As SG A:Csr12 2.21 As O1 A:Csr12 1.70 As AS A:Csr12 0.00 As C A:Csr12 3.75 As O3 A:Csr12 1.69 As CA A:Csr12 3.42 As N A:Gly13 3.73 As C A:Gly13 4.82 As CA A:Gly13 4.72 As N A:Thr14 3.92 As CB A:Thr14 4.23 As OG1 A:Thr14 3.92 As CA A:Thr14 4.69 As CZ A:Arg94 3.40 As CZ A:Arg94 4.44 As NE A:Arg94 4.12 As NE A:Arg94 4.02 As NH2 A:Arg94 3.14 As NH2 A:Arg94 3.82 As NH1 A:Arg94 3.58 As CZ A:Arg107 4.87 As NH2 A:Arg107 4.68 As NH1 A:Arg107 4.06 As S A:So4201 2.90 As O1 A:So4201 2.88 As O2 A:So4201 3.61 As O4 A:So4201 4.15 As O3 A:So4201 2.04 As O A:Hoh1281 4.61 As O A:Hoh1303 3.07 interactive model:
