In the absence of autoinducer 2 (AI-2), represses transcription of the lsrACDBFG operon and its own transcription. In the presence of AI-2, LsrR is inactivated by binding phospho-AI-2, leading to the transcription of the lsr genes.<ref>PMID:15601708</ref> <ref>PMID:15743955</ref> <ref>PMID:17557827</ref> | ||
