== Function == | |||
[https://www.uniprot.org/uniprot/RHLR_PSEAE RHLR_PSEAE] Quorum-sensing regulator that controls the expression of multiple virulence factors in response to extracellular signaling molecules called autoinducers (PubMed:7494482, PubMed:8522523, PubMed:15576196). Involved, among others, in the transcriptional regulation of genes that are responsible for rhamnolipid surfactant biosynthesis (PubMed:8144472, PubMed:7604006, PubMed:14526008). Acts by binding to a specific sequence in the rhlAB regulatory region, both in the presence and in the absence of its autoinducer (PubMed:14526008). In the former case it activates transcription of the promoter, whereas in the latter it acts as a transcriptional repressor (PubMed:14526008). Also regulates the expression of the rmlBDAC operon, encoding dTDP-L-rhamnose biosynthetic enzymes, by binding to the rml box in the promoter region (PubMed:22262098). In addition, is involved in the regulation of the production of elastase (lasB) and pyocyanine (PubMed:8144472, PubMed:7604006, PubMed:8522523).<ref>PMID:14526008</ref> <ref>PMID:15576196</ref> <ref>PMID:22262098</ref> <ref>PMID:7494482</ref> <ref>PMID:7604006</ref> <ref>PMID:8144472</ref> <ref>PMID:8522523</ref> | |||
