Sodium in the structure of Tryptophan Synthase in Complex With N-(4'- Trifluoromethoxybenzoyl)-2-Amino-1-Ethylphosphate (F6) - LOWF6 Complex (pdb 2cle)

The binding sites of Sodium atom in the structure of Tryptophan Synthase in Complex With N-(4'- Trifluoromethoxybenzoyl)-2-Amino-1-Ethylphosphate (F6) - LOWF6 Complex (pdb code 2cle). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2cle 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) 19.9-1.5 Space group C121 a (A) 182.364 b (A) 59.621 c (A) 67.248 alpha (°) 90.00 beta (°) 94.73 gamma (°) 90.00 Rfactor (%) 19.4 Rfree (%) 21 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2cle Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2cle.
