Sodium in the structure of Crystal Structure Of A Section of A De Novo Design Gigadalton Protein Fibre (pdb 3ra3)

The binding sites of Sodium atom in the structure of Crystal Structure Of A Section of A De Novo Design Gigadalton Protein Fibre (pdb code 3ra3). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3ra3 structure was solved by N.R.ZACCAI, T.H.SHARP, M.BRUNING, D.N.WOOLFSON, R.L.BRADY, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 22.5-2.3 Space group P32 a (A) 45.082 b (A) 45.082 c (A) 67.593 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) 18.8 Rfree (%) 24.8 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3ra3 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3ra3.
