About: Ada regulon

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In DNA repair, the Ada regulon is a set of genes whose expression is essential to adaptive response (also known as "Ada response", hence the name), which is triggered in prokaryotic cells by exposure to sub-lethal doses of alkylating agents. This allows the cells to tolerate the effects of such agents, which are otherwise toxic and mutagenic. The Ada response includes the expression of four genes: ada, alkA, alkB, and aidB. The product of ada gene, the Ada protein, is an activator of transcription of all four genes. DNA bases damaged by alkylation are removed by distinct strategies.
