Sodium in the structure of Crystal Structure of Phosphate-Bound Adenylosuccinate Lyase From E. Coli (pdb 3gzh)

The binding sites of Sodium atom in the structure of Crystal Structure of Phosphate-Bound Adenylosuccinate Lyase From E. Coli (pdb code 3gzh). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3gzh structure was solved by G.KOZLOV, K.GEHRING, MONTREAL-KINGSTON BACTERIAL STRUCTURAL GENOMICSINITIATIVE (BSGI), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 50.0-1.9 Space group I222 a (A) 77.316 b (A) 100.256 c (A) 150.104 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 17 Rfree (%) 21.4 Sodium Binding Sites: Sodium binding site 1 out of 2 in 3gzh Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3gzh.
