Arsenic in the structure of Structural Insights Into Cis Element Recognition of Non- Polyadenylated Rnas By the NAB3-Rrm (pdb 2xnq)

The binding sites of Arsenic atom in the structure of Structural Insights Into Cis Element Recognition of Non- Polyadenylated Rnas By the NAB3-Rrm (pdb code 2xnq). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 2xnq structure was solved by B.M.LUNDE, M.HORNER, A.MEINHART, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 33.6-1.3 Space group P212121 a (A) 26.950 b (A) 42.070 c (A) 55.670 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17.466 Rfree (%) 19.448 Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 2xnq Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 2xnq. 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: Glu382, A: Caf383, A: Hoh2032, conact list: Atom Atom Distance (A) As O A:Glu382 4.87 As C A:Glu382 4.89 As O A:Caf383 4.58 As N A:Caf383 4.42 As CB A:Caf383 3.11 As CE2 A:Caf383 1.99 As SG A:Caf383 2.27 As O1 A:Caf383 1.95 As AS A:Caf383 0.00 As C A:Caf383 4.61 As CE1 A:Caf383 1.98 As CA A:Caf383 3.54 As O A:Hoh2032 4.64 interactive model:
