Bromine in the structure of Structure of the Escherichia Coli Clc Chloride Channel Y445A Mutant and Fab Complex (pdb 2htk)

The binding sites of Bromine atom in the structure of Structure of the Escherichia Coli Clc Chloride Channel Y445A Mutant and Fab Complex (pdb code 2htk). This binding sites where shown with 5.0 Angstroms radius around Bromine atom. The 2htk structure was solved by A.ACCARDI, S.LOBET, C.WILLIAMS, C.MILLER, R.DUTZLER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 40.0-3.4 Space group C121 a (A) 232.067 b (A) 98.139 c (A) 171.068 alpha (°) 90.00 beta (°) 131.56 gamma (°) 90.00 Rfactor (%) 26.6 Rfree (%) 27.6 Bromine Binding Sites: Bromine binding site 1 out of 2 in 2htk Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Bromine in the PDB 2htk.
