Sodium in the structure of Structure Of Wild-Type E. Coli Aspartate Transcarbamoylase in the Presence of Ctp, Carbamoyl Phosphate At 2.50 A Resolution (pdb 1za2)

The binding sites of Sodium atom in the structure of Structure Of Wild-Type E. Coli Aspartate Transcarbamoylase in the Presence of Ctp, Carbamoyl Phosphate At 2.50 A Resolution (pdb code 1za2). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1za2 structure was solved by J.WANG, K.A.STIEGLITZ, J.P.CARDIA, E.R.KANTROWITZ, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-2.5 Space group P321 a (A) 121.442 b (A) 121.442 c (A) 142.547 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 19.7 Rfree (%) 25.1 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1za2 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1za2. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Sodium atom, shown by VdW sphere Residues shown as a stick model or VDW spheres: A: His64, A: Ser69, A: Hoh323, A: Hoh379, A: Hoh391, A: Hoh450, conact list: Atom Atom Distance (A) Na ND1 A:His64 4.55 Na CE1 A:His64 4.42 Na CB A:Ser69 4.72 Na OG A:Ser69 3.98 Na CA A:Ser69 4.73 Na O A:Hoh323 2.99 Na O A:Hoh379 2.20 Na O A:Hoh391 4.53 Na O A:Hoh450 3.25 interactive model:
