Sodium in the structure of Crystal Structure of the Serratia Marcescens Chitin-Binding Protein CBP21 (pdb 2bem)

The binding sites of Sodium atom in the structure of Crystal Structure of the Serratia Marcescens Chitin-Binding Protein CBP21 (pdb code 2bem). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2bem structure was solved by G.VAAJE-KOLSTAD, D.R.HOUSTON, V.G.H.EIJSINK, D.M.F.VAN AALTEN, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 24.2-1.6 Space group P212121 a (A) 51.936 b (A) 58.053 c (A) 159.829 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 15.6 Rfree (%) 17.5 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2bem Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2bem.
