Sodium in the structure of Crystal Structure of A Marr Family Transcriptional Regulator (CD1569) From Clostridium Difficile 630 At 2.20 A Resolution (pdb 3nqo)

The binding sites of Sodium atom in the structure of Crystal Structure of A Marr Family Transcriptional Regulator (CD1569) From Clostridium Difficile 630 At 2.20 A Resolution (pdb code 3nqo). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3nqo structure was solved by JOINT CENTER FOR STRUCTURAL GENOMICS (JCSG), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 29.7-2.2 Space group P212121 a (A) 69.739 b (A) 72.672 c (A) 76.072 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 19.7 Rfree (%) 23.7 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3nqo Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3nqo.
