| - | The Escherichia coli enzyme 3-methyladenine DNA glycosylase I (TAG) hydrolyzes the glycosidic bond of 3-methyladenine (3-MeA) in DNA and is found in many bacteria and some higher eukaryotes. TAG shows little primary sequence identity with members of the well-known helix-hairpin-helix (HhH) superfamily of DNA repair glycosylases, which consists of AlkA, EndoIII, MutY and hOGG1. Unexpectedly, the three-dimensional solution structure reported here reveals TAG as member of this superfamily. The restricted specificity of TAG for 3-MeA bases probably arises from its unique aromatic rich 3-MeA binding pocket and the absence of a catalytic aspartate that is present in all other HhH family members. | ||
