Identification
Name: 2-heptyl-3-hydroxy-4-quinolone
Description:

The Pseudomonas quinolone signal (PQS) is a quorum sensing molecule unique to Pseudomonas aeruginosa. This molecule is active when the density of bacterial cells reaches a quorum. PQS is an important signaling molecule that enhances the production of virulence factors by P. aeruginosa including the production of phenazines and elastases. PQS has also been reported to chelate ferric iron and induce vesicle formation at the membrane. PQS is produced from the hydroxylation of HHQ by mono-oxygenase PqsH.
