Sodium in the structure of Design of Stable Alpha-Helical Arrays From An Idealized Tpr Motif (pdb 1na0)

The binding sites of Sodium atom in the structure of Design of Stable Alpha-Helical Arrays From An Idealized Tpr Motif (pdb code 1na0). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1na0 structure was solved by E.MAIN, Y.XIONG, M.COCCO, L.D'ANDREA, L.REGAN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 33.9-1.6 Space group C121 a (A) 102.734 b (A) 46.560 c (A) 52.517 alpha (°) 90.00 beta (°) 99.11 gamma (°) 90.00 Rfactor (%) 18.3 Rfree (%) 21.6 Sodium Binding Sites: Sodium binding site 1 out of 2 in 1na0 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1na0.
