This domain is found at the C-terminal end of transcriptional regulators of the TetR family, including Swiss:O53623 from Mycobacterium tuberculosis and Swiss:Q1D4I5 from Myxococcus xanthus. This is the all-helical ligand-binding domain, which interacts with the respective effector molecule and transmits the signal to the DNA binding domain (Pfam:PF00440).	Domain
