Application

N-(3-Oxododecanoyl)-L-homoserine lactone (3-Oxo-C12-HSL), a member of a family of acyl homoserine lactones, may be used to determine its mechanisms and specificity of action as a signaling molecule involved in the regulation of bacterial quorum sensing.

Biochem/physiol Actions

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

The arms race between bacteria and phages has led to the evolution of diverse anti-phage defenses, several of which are controlled by quorum-sensing pathways. In this work, we characterize a quorum-sensing anti-activator protein, Aqs1, found in Pseudomonas phage DMS3. We
