Comment(s) |
- Acyl-homoserine lactones (AHLs) are produced by a number of bacterial
species and are used by them to regulate the expression of virulence
genes in a process known as quorum-sensing.
- Each bacterial cell has a basal level of AHL and, once the population
density reaches a critical level, it triggers AHL-signaling which,
in turn, initiates the expression of particular virulence genes.
- Plants or animals capable of degrading AHLs would have a therapeutic
advantage in avoiding bacterial infection as they could prevent AHL-
signaling and the expression of virulence genes in quorum-sensing
bacteria.
- N-(3-oxohexanoyl)-L-homoserine lactone, N-(3-oxododecanoyl)-L-
homoserine lactone, N-butanoyl-L-homoserine lactone and
N-(3-oxooctanoyl)-L-homoserine lactone can act as substrates.
