Sodium in the structure of Crystal Structure of Peptide Abc Transporter, Peptide-Binding Protein (pdb 3o6p)

The binding sites of Sodium atom in the structure of Crystal Structure of Peptide Abc Transporter, Peptide-Binding Protein (pdb code 3o6p). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3o6p structure was solved by C.CHANG, L.BIGELOW, J.BEARDEN, A.JOACHIMIAK, MIDWEST CENTER FORSTRUCTURAL GENOMICS (MCSG), with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 44.5-1.6 Space group P212121 a (A) 50.733 b (A) 53.653 c (A) 79.498 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 14.9 Rfree (%) 20 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3o6p Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3o6p.
