The binding sites of Magnesium atom in the structure of O6-Methyl-Guanine:T Pair in the Polymerase-10 Basepair Position (pdb code 2hhq). This binding sites where shown with 5.0 Angstroms radius around Magnesium atom. The 2hhq structure was solved by J.J.WARREN, L.J.FORSBERG, L.S.BEESE, with X-Ray Crystallography technique, brief refinement statistics is given in the table below:
