Rubidium in the structure of A "Hydrat-Ion Spine" in A B-Dna Minor Groove (pdb 461d)

The binding sites of Rubidium atom in the structure of A "Hydrat-Ion Spine" in A B-Dna Minor Groove (pdb code 461d). This binding sites where shown with 5.0 Angstroms radius around Rubidium atom. The 461d structure was solved by V.TERESHKO, G.MINASOV, M.EGLI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 20.0-1.5 Space group P212121 a (A) 25.070 b (A) 39.720 c (A) 65.770 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 18.6 Rfree (%) n/a Rubidium Binding Sites: Rubidium binding site 1 out of 1 in 461d Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Rubidium in the PDB 461d.
