Sodium in the structure of Crystal Structure Of The Complex of Bacterial Tryptophan Synthase With the Transition State Analogue Inhibitor 4-(2-Hydroxy-4- Fluorophenylthio)-Butylphosphonic Acid (pdb 1c9d)

The binding sites of Sodium atom in the structure of Crystal Structure Of The Complex of Bacterial Tryptophan Synthase With the Transition State Analogue Inhibitor 4-(2-Hydroxy-4- Fluorophenylthio)-Butylphosphonic Acid (pdb code 1c9d). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1c9d structure was solved by E.LOLIS, A.SACHPATZIDIS, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 30.0-2.3 Space group C121 a (A) 184.220 b (A) 60.520 c (A) 67.790 alpha (°) 90.00 beta (°) 94.43 gamma (°) 90.00 Rfactor (%) 21.1 Rfree (%) 26.9 Sodium Binding Sites: Sodium binding site 1 out of 1 in 1c9d Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1c9d. 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: B: Val231, B: Gly232, B: Gly233, B: Glu256, B: Gly268, B: Pro270, B: Ser297, B: Leu304, B: Phe306, B: Pro307, B: Ser308, B: Val309, B: Hoh1028, B: Hoh1131, conact list: Atom Atom Distance (A) Na O B:Val231 4.43 Na O B:Gly232 2.39 Na C B:Gly232 3.55 Na CA B:Gly232 4.22 Na N B:Gly233 4.65 Na CA B:Gly233 4.95 Na OE2 B:Glu256 4.91 Na O B:Gly268 4.22 Na CD B:Pro270 3.99 Na CG B:Pro270 3.89 Na OG B:Ser297 4.63 Na O B:Leu304 4.88 Na O B:Phe306 2.29 Na N B:Phe306 4.65 Na CB B:Phe306 4.16 Na CD1 B:Phe306 4.40 Na C B:Phe306 3.47 Na CG B:Phe306 4.72 Na CA B:Phe306 4.30 Na N B:Pro307 4.43 Na C B:Pro307 4.50 Na CA B:Pro307 4.66 Na O B:Ser308 2.51 Na N B:Ser308 3.96 Na C B:Ser308 3.71 Na CA B:Ser308 4.45 Na N B:Val309 4.71 Na CB B:Val309 4.85 Na CA B:Val309 4.83 Na O B:Hoh1028 2.29 Na O B:Hoh1131 2.29 interactive model:
