Sodium in the structure of 2.0A X-Ray Structure Of C-Terminal Kinase Domain of P90 Ribosomal S6 Kinase 2 (RSK2) (pdb 2qr8)

The binding sites of Sodium atom in the structure of 2.0A X-Ray Structure Of C-Terminal Kinase Domain of P90 Ribosomal S6 Kinase 2 (RSK2) (pdb code 2qr8). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 2qr8 structure was solved by V.TERESHKO, M.MALAKHOVA, Z.DONG, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-2.0 Space group P41212 a (A) 46.912 b (A) 46.912 c (A) 291.076 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 21.5 Rfree (%) 25.9 Sodium Binding Sites: Sodium binding site 1 out of 1 in 2qr8 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 2qr8.
