Sodium in the structure of Crystal Structure of Cytidylyltransferase From Vibrio Cholerae (pdb 3oam)

The binding sites of Sodium atom in the structure of Crystal Structure of Cytidylyltransferase From Vibrio Cholerae (pdb code 3oam). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3oam structure was solved by J.HATTNE, D.BOREK, S.GRIMSHAW, C.NAKKA, R.ROSTANKOWSKI, Z.OTWINOWSKI, CENTER FOR STRUCTURAL GENOMICS OF INFECTIOUS DISEASES (CSGID), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 25.1-1.8 Space group P1 a (A) 58.928 b (A) 68.209 c (A) 71.476 alpha (°) 82.73 beta (°) 74.19 gamma (°) 76.97 Rfactor (%) 19.8 Rfree (%) 23.2 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3oam Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3oam.
