Sodium in the structure of 1.8 Angstroms Crystal Structure Of the C-Terminal Domain of Rabbit Serum Hemopexin (pdb 1hxn)

The binding sites of Sodium atom in the structure of 1.8 Angstroms Crystal Structure Of the C-Terminal Domain of Rabbit Serum Hemopexin (pdb code 1hxn). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 1hxn structure was solved by H.R.FABER, E.N.BAKER, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.8 Space group P212121 a (A) 43.600 b (A) 62.800 c (A) 80.600 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) n/a Rfree (%) n/a Sodium Binding Sites: Sodium binding site 1 out of 2 in 1hxn Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 1hxn.
