In ''Pseudomonas aeruginosa'' PAO1, HSL signal molecules need to form a complex with rhlr to start the downstream gene transcription. We knock out genes related to HSL signal molecules and PQS signal molecules, and find that when HSL signal is missing, PA2069 loses its β-Galactosidase activity, that is, PA2069 is the promoter responding to HSL.

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 (HSL).


Usage and Biology

In Pseudomonas aeruginosa PAO1, HSL signal molecules need to form a complex with rhlr to start the downstream gene transcription. We knock out genes related to HSL signal molecules and PQS signal molecules, and find that when HSL signal is missing, PA2069 promoter loses its β-Galactosidase activity, that is, PA2069 is the promoter responding to HSL.
