Sodium in the structure of A Heterospecific Leucine Zipper Tetramer (pdb 3crp)

The binding sites of Sodium atom in the structure of A Heterospecific Leucine Zipper Tetramer (pdb code 3crp). This binding sites where shown with 5.0 Angstroms radius around Sodium atom. The 3crp structure was solved by J.LIU, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 25.1-1.7 Space group P4212 a (A) 79.473 b (A) 79.473 c (A) 54.947 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 20.3 Rfree (%) 23 Sodium Binding Sites: Sodium binding site 1 out of 1 in 3crp Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Sodium in the PDB 3crp.
