[[http://www.uniprot.org/uniprot/ADA_ECOLI ADA_ECOLI]] Is involved in the adaptive response to alkylation damage in DNA caused by alkylating agents. Repairs O6-methylguanine and 04-methylthymine residues in alkylated DNA by a direct and irreversible transfer of the methyl group from the base to one of its own cysteine residues (Cys-321). Also specifically repairs the Sp diastereomer of DNA methylphosphotriester lesions by the same mechanism, although the methyl transfer occurs onto a different cysteine residue (Cys-38). Can not demethylate the other diastereomer, Rp-methylphosphotriester.<ref>PMID:2987862</ref> The methylation of Ada by methylphosphotriesters in DNA leads to its activation as a transcriptional regulator that activates the transcription of its own gene, ada, and other alkylation resistance genes, alkA, alkB and aidB.<ref>PMID:2987862</ref>
