Pseudomonas Quinolone Signal. Our group proposed the bilayer. Aeruginosa but not in samples from uninfected patients. Pseudomonas aeruginosa produces 2-heptyl-3-hydroxy-41H-quinolone PQS a quorum-sensing QS signal that regulates numerous virulence genes including those involved in iron scavengingBiophysical analysis revealed that 2-alkyl-3-hydroxy-4-quinolones form complexes with ironIII at physiological pH. Because OMVs have been implicated in many virulence-associated behaviors it is critical that we understand how they are formed.

Aeruginosa produces another signal molecule 2-heptyl-3-hydroxy-4-quinolone which has been designated as the Pseudomonas quinolone signal. The Pseudomonas quinolone signal PQS and its precursor 2-heptyl-4-quinolone HHQ play a key role in coordinating virulence in the important cystic fibrosis pathogen Pseudomonas aeruginosaThe discovery of HHQ analogues in Burkholderia and other microorganisms led us to investigate the possiblity that these compounds can influence interspecies behaviour. For example it causes chronic pneumonia in cystic fibrosis patients. PQS can induce both lasB encodes LasB elastase and rhlI encodes the C 4 -HSL synthase in P. This signal controls multiple virulence factors and is intertwined in the quorum-sensing cascade where it appears to be a regulatory link between the las and rhl quorum-sensing.
