Part:BBa_K1315001

The pqsA promoter from Pseudomonas

This is a promoter from Pseudomonas aeruginosa that is positively regulated when the transcription factor PqsR BBa_K1157001 is activated by PQS (Pseudomonas Quinolone Signal).

Usage and Biology

The Pseudomonas quinolone signal (PQS) is imperative in modulating mechanisms that enable Pseudomonas aeruginosa to survive at times of stress. P. aeruginosa is the main pathogen responsible for severe deterioration in the Cystic Fibrosis lungs. The production of this signal relies on the pqsABCDE operon. The transcriptional factor PqsR (BBa_K1315000) positively regulates this operon.
