Sodium in the structure of Tryptophan Synthase in Complex With N-(4'- Trifluoromethoxybenzoyl)-2-Amino-1-Ethylphosphate (F6) - HIGHF6 Complex (pdb 2clf)

The binding sites of Sodium atom in the structure of Tryptophan Synthase in Complex With N-(4'- Trifluoromethoxybenzoyl)-2-Amino-1-Ethylphosphate (F6) - HIGHF6 Complex (pdb code 2clf). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2clf structure was solved by H.NGO, R.HARRIS, N.KIMMICH, P.CASINO, D.NIKS, L.BLUMENSTEIN, T.R.BARENDS, V.KULIK, M.WEYAND, I.SCHLICHTING, M.F.DUNN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 19.1-1.7 Space group C121 a (A) 182.840 b (A) 58.989 c (A) 67.423 alpha (°) 90.00 beta (°) 94.78 gamma (°) 90.00 Rfactor (%) 17.6 Rfree (%) 19.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2clf Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2clf.
