This domain is named after the various transcriptional regulatory proteins that it contains, including MtrR (Swiss:Q6RV06), AcrR (Swiss:P34000), ArpR (Swiss:Q9KJC4), TtgR (Swiss:Q9AIU0) and SmeT (Swiss:Q8KLP4). These are members of the TetR family of transcriptional repressors, that are involved in the control of expression of multidrug resistance proteins [1,2,3]. This domain binds multiple drugs, antibiotics, flavonoids and indole (Matilla et. al., FEMS Microbiology Reviews, fuab043, 45, 2021, 1. https://doi.org/10.1093/femsre/fuab043).	Domain
