Arsenic in the structure of Crystal Structure of An 'All Locked' Lna Duplex At 1.9 Angstrom Resolution (pdb 2x2q)

The binding sites of Arsenic atom in the structure of Crystal Structure of An 'All Locked' Lna Duplex At 1.9 Angstrom Resolution (pdb code 2x2q). This binding sites where shown with 5.0 Angstroms radius around Arsenic atom. The 2x2q structure was solved by A.EICHERT, K.BEHLING, J.P.FUERSTE, C.BETZEL, V.A.ERDMANN, C.FOERSTER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 39.0-1.9 Space group C121 a (A) 77.913 b (A) 40.737 c (A) 30.059 alpha (°) 90.00 beta (°) 91.02 gamma (°) 90.00 Rfactor (%) 22.353 Rfree (%) 26.37 Arsenic Binding Sites: Arsenic binding site 1 out of 1 in 2x2q Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Arsenic in the PDB 2x2q.
