Biochem/physiol Actions

N-Heptanoyl-DL-homoserine lactone (C7HSL) is among a group of homoserine lactones that includes; N-octanoyl-homoserine lactone (N-C8-HSL), N-Decanoyl-DL-homoserine lactone (N-C10-HSL), N-(3-oxodecanoyl) homoserine-L-lactone (3-oxo-C10 HSL), N-(3-oxododecanoyl)homoserine-L-lactone (3-oxo-C12-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.
N-Heptanoyl-DL-homoserine lactone is a member of N-acyl-homoserine lactone family. N-acylhomoserine lactones (AHL) regulate gene expression in gram-negative bacteria, such asEcherichia and Salmonella are involved in quorum sensing, cell to cell communication among bacteria. Some AHLs are potent chemoattractants for human immune cells such as neutrophils.

Intercellular communication by means of small signal molecules coordinates gene expression among bacteria. This population density-dependent regulation is known as quorum sensing. The symbiotic nitrogen-fixing bacterium Sinorhizobium meliloti Rm1021 possesses the Sin quorum sensing system based on N-acyl homoserine lactones...

In tests, Chromobacterium violaceum ATCC 12472 produced several N-acyl-L-homoserine lactones (AHLs). Of these, N-(3-hydroxydecanoyl)-L-homoserine lactone was dominant, and controlled violacein production by quorum sensing. Strain VIR07, an AHL-deficient mutant, did not produce violacein. Violacein production in VIR07 was induced by...
