Magnesium in the structure of The Crystal Structure of E. Coli Muts Binding to Dna With A C:A Mismatch (pdb 1oh5)

The binding sites of Magnesium atom in the structure of The Crystal Structure of E. Coli Muts Binding to Dna With A C:A Mismatch (pdb code 1oh5). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 1oh5 structure was solved by G.NATRAJAN, M.H.LAMERS, J.H.ENZLIN, H.H.K.WINTERWERP, A.PERRAKIS, T.K.SIXMA, with X-Ray Crystallography technique, brief refinement statistics is given in the table below: Resolution (A) 15.0-2.9 Space group P212121 a (A) 89.913 b (A) 91.887 c (A) 261.173 alpha (°) 90.00 beta (°) 90.00 gamma (°) 90.00 Rfactor (%) 22.4 Rfree (%) 29.4 Magnesium Binding Sites: Magnesium binding site 1 out of 1 in 1oh5 Click to enlarge Click to enlarge Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Magnesium in the PDB 1oh5.
