Protein
HTH-type quorum sensing-dependent transcriptional regulator RpaR
Organism
Rhodopseudomonas palustris (strain ATCC BAA-98 / CGA009)
Function
Responds to the quorum-sensing autoinducer 4-coumaroyl-homoserine lactone to regulate expression of several genes. Represses expression of rpaI in the absence of the inducer.
Similarity
Belongs to the autoinducer-regulated transcriptional regulatory protein family.
