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-signalling which, in turn, initiates the expression of particular virulence genes . N-(3-Oxohexanoyl)-[acyl-carrier protein] and hexanoyl-[acyl-carrier protein] are the best substrates . The fatty-acyl substrate is derived from fatty-acid biosynthesis through acyl-[acyl-carrier protein] rather than from fatty-acid degradation through acyl-CoA . S-Adenosyl-L-methionine cannot be replaced by methionine, S-adenosylhomocysteine, homoserine or homoserine lactone .

SYSTEMATIC NAME
IUBMB Comments
acyl-[acyl-carrier protein]:S-adenosyl-L-methionine acyltranserase (lactone-forming, methylthioadenosine-releasing)
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-signalling which, in turn, initiates the expression of particular virulence genes [5]. N-(3-Oxohexanoyl)-[acyl-carrier protein] and hexanoyl-[acyl-carrier protein] are the best substrates [1]. The fatty-acyl substrate is derived from fatty-acid biosynthesis through acyl-[acyl-carrier protein] rather than from fatty-acid degradation through acyl-CoA [1]. S-Adenosyl-L-methionine cannot be replaced by methionine, S-adenosylhomocysteine, homoserine or homoserine lactone [1].

the LasR protein of Pseudomonas aeruginosa is a central component of a regulatory web that controls the expression of hundreds of genes, some of which play direct roles in disease, molecular mechanism of action of LasR as transcription factor, it detects 3-oxododecanoyl-L-homoserine lactone, overview. The so-called orphan receptor QscR, which also detects 3-oxododecanoyl-L-homoserine lactone. The second quorum sensing receptor, RhlR, detects butanoyl-L-homoserine lactone and interacts with its cognate AHL synthase, RhlI. Unlike LuxR, LasR does not detectably release its N-acyl-homoserine lactone. It binds to six LasR-dependent promoters

RsaLWCS does not show a repressive effect on the promoter of the QS signal synthase gene lasI in Pseudomonas aeruginosa. RsaLWCS formed stable complexes with the promoter of lasI, the gene orthologous to ppuI. RsaLWCS regulates siderophore-mediated growth limitation of plant pathogens and biofilm formation, two processes relevant for plant growth-promoting activity. RsaL binds close to LasR on the same bidirectional promoter, repressing the transcription of both the lasI and rsaL genes. Molecular mechanism, overview

degradation
-
a significant positive correlation is observed between isoform LasI expression and polycyclic aromatic hydrocarbon degradation. Expression of isoform LasI increases with increase in biofilm growth, while the expression of isoform RhlI decreases during log phase of biofilm growth. Degradation of phenanthrene and pyrene by Pseudomonas aeruginosa N6P6 is affected by biofilm growth and LasI expression. The respective phenanthrene degradation for 15, 24, 48, and 72 h old biofilm after 7 days is 21.5, 54.2, 85.6, and 85.7%. The corresponding pyrene degradation is 15, 18.28, 47.56, and 46.48%, respectively, after 7 days
