Sodium in the structure of The 1.40 A Structure of Spacehab-01 Hen Egg White Lysozyme (pdb 194l)

The binding sites of Sodium atom in the structure of The 1.40 A Structure of Spacehab-01 Hen Egg White Lysozyme (pdb code 194l). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 194l 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) 7.0-1.4 Space group P43212 a (A) 78.650 b (A) 78.650 c (A) 37.760 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.3 Rfree (%) 22.6 Sodium Binding Sites: Sodium binding site 1 out of 1 in 194l Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 194l.
