CC   -!- FUNCTION: Regulates transcription of many different genes. In the
CC       absence of autoinducer 2 (AI-2), represses transcription of the
CC       lsrACDBFG operon and its own transcription. In the presence of AI-2,
CC       LsrR is inactivated by binding phospho-AI-2, leading to the
CC       transcription of the lsr genes (By similarity). {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}.
