Arsenic in the structure of Pentameric Ligand Gated Ion Channel Glic in Complex With Tetramethylarsonium (Tmas) (pdb 2xq4)

The binding sites of Arsenic atom in the structure of Pentameric Ligand Gated Ion Channel Glic in Complex With Tetramethylarsonium (Tmas) (pdb code 2xq4). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 2xq4 structure was solved by R.J.C.HILF, C.BERTOZZI, I.ZIMMERMANN, A.REITER, D.TRAUNER, R.DUTZLER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 40.2-3.6 Space group C121 a (A) 183.314 b (A) 128.310 c (A) 164.374 alpha (°) 90.00 beta (°) 104.04 gamma (°) 90.00 Rfactor (%) 25.92 Rfree (%) 27.22 Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 2xq4 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 2xq4.
