Sodium in the structure of The 1.33 A Structure of Tetragonal Hen Egg White Lysozyme (pdb 193l)

The binding sites of Sodium atom in the structure of The 1.33 A Structure of Tetragonal Hen Egg White Lysozyme (pdb code 193l). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 193l structure was solved by M.C.VANEY, S.MAIGNAN, M.RIES-KAUTT, A.DUCRUIX, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 7.0-1.3 Space group P43212 a (A) 78.540 b (A) 78.540 c (A) 37.770 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.4 Rfree (%) 22.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 193l Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 193l.
