      The cellular methyl donor S-adenosylmethionine (SAM) and other endo/exogenous agents methylate DNA bases non-enzymatically into products interfering with replication and transcription. An important product is 3-methyladenine (m<sup>3</sup>A), which in <i>Escherichia coli</i> is removed by m<sup>3</sup>A-DNA glycosylase I (Tag) and II (AlkA). The <i>tag</i> gene is constitutively expressed, while ...
