Representation of the regulatory domain patterns, the alkyltransferase of the Ada, and the Ogt proteins in Bacteria. The regulatory portion of ada is represented by blue and gray boxes, respectively the DNA binding (ada-zinc binding site) and transcriptional activation (HTH-AraC) domains. The alkyltransferase domain, also present in the Ogt protein, is represented by pink boxes. The green box characterizes the AlkA domain, which is involved in the removal of alkyl groups in the base excision repair pathway. The AlkA protein is fused to the regulatory portion of Ada protein in some organisms, as shown.
