PA2069 Promoter

This part is a promoter which is regulated by the quorum sensing system in Pseudomonas aeruginosa, and the signal molecule which regulates the promoter is N-(butyry1)-1-homoserine lactone (BHL).


Usage and Biology

BHL and RhlR are self-inducing signaling molecules and receptor pairs for the P. aeruginosa Quorum sensing. When BHL and RhlR form a complex, they can induce downstream gene transcription.When our team knocks out rhlR gene and rhlI gene separately, PA2069 promoter The enzyme activity was significantly reduced, so the PA2069 promoter was transformed in response to BHL-RhlR.
