Description

Biochem/physiol Actions

Acyl homoserine lactone that is an autoinducer of quorum sensing by Pseudomonas aeruginosa.1 Degraded by paraoxonase (PON) family members.2

N-(3-oxododecanoyl)homoserine-L-lactone (3-oxo-C12-HSL) is among a group of homoserine lactones that includes; N-octanoyl-homoserine lactone (N-C8-HSL), N-(3-oxodecanoyl) homoserine-L-lactone (3-oxo-C10 HSL), N-(3-Oxotetradecanoyl)-L-homoserine lactone (3-oxo-C14-HSL, N-(3-hydroxydecanoyl)-L-homoserine lactone, and N-(3-hydroxyoctanoyl)-L-homoserine lactone involved in the processes of bacterial quorum sensing. These N-acyl-homoserine lactones are used to study the processes and mechanisms of bacterial quorum sensing.
