This entry represents the C-terminal domain found in a group of TetR transcription regulators, including YxaF (also known as T1414) [1] and LmrA from Bacillus subtilis, which are paralogous to each other [2]. LmrA and YxaF are repressors that bind specifically to almost the same cis sequences, LmrA/YxaF boxes, located in the promoter regions of the lmrAB operon, the yxaF gene, and the yxaGH operon [2].
