Magnesium in the structure of Crystal Structure of A Luteoviral Rna Pseudoknot and Model For A Minimal Ribosomal Frameshifting Motif (pdb 2a43)

The binding sites of Magnesium atom in the structure of Crystal Structure of A Luteoviral Rna Pseudoknot and Model For A Minimal Ribosomal Frameshifting Motif (pdb code 2a43). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 2a43 structure was solved by P.S.PALLAN, W.S.MARSHALL, J.HARP, F.C.JEWETT III, Z.WAWRZAK, B.A.BROWN II, A.RICH, M.EGLI, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 23.6-1.3 Space group P3221 a (A) 53.250 b (A) 53.250 c (A) 55.000 alpha (°) 90.00 beta (°) 90.00 gamma (°) 120.00 Rfactor (%) n/a Rfree (%) n/a Magnesium Binding Sites: Magnesium binding site 1 out of 2 in 2a43 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 2a43.
