This is the N-terminal domain of Adaptive response protein AidB present in E. coli. AidB is upregulated in response to small doses of DNA-methylating agents initiates a response that mitigates the mutagenic and cytotoxic effects of DNA methylation. Tetramer formation is thought to be carried out by the N-terminal domain [1].	Domain
