General description

HHQ belongs to 2-alkyl-4-quinolone compounds, which are lipophilic and are slightly soluble in water.

Biochem/physiol Actions

HHQ or 2-Heptyl-4-quinolone is a modulator of swarm motility. HHQ can be converted to PQS (Pseudomonas quinolone signal) by the PqsH protein.
HHQ stimulates vesicle formation but not as much as PQS.

The bacterium Burkholderia thailandensis produces an arsenal of secondary metabolites that have diverse structures and roles in the ecology of this soil-dwelling bacterium. In coculture experiments, B. thailandensis strain E264 secretes an antimicrobial that nearly eliminates another soil bacterium, Bacillus
