Formation of a covalent complex between methylguanine methyltransferase and DNA via disulfide bond formation between the active site cysteine and a thiol-containing analog of guanine.

DNA repair methyltransferases (MTases) remove methyl or other alkyl groups from the O6 position of guanine or the O4 position of thymine by transfering the group to an active site cysteine. In order to trap an MTase-DNA complex via a disulfide bond, 2'-deoxy-6-(cystamine)-2-aminopurine (d6Cys2A...
