CC   -!- FUNCTION: In the absence of autoinducer 2 (AI-2), represses
CC       transcription of the lsrACDBFGE operon and its own transcription. In
CC       the presence of AI-2, LsrR is inactivated by binding phospho-AI-2,
CC       leading to the transcription of the lsr genes (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- INDUCTION: Autoregulated. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the SorC transcriptional regulatory family.
CC       {ECO:0000305}.
