Deciphering Physiological Functions of AHL Quorum Quenching Acylases

Frontiers in Microbiology, 2017
N-Acylhomoserine lactone (AHL)-acylase (also known as amidase or amidohydrolase) is a class of enzyme that belongs to the Ntn-hydrolase superfamily. As the name implies, AHL-acylases are capable of hydrolysing AHLs, the most studied signaling molecules ...

Communication in bacteria: an ecological and evolutionary perspective [PDF]

, 2006
Individual bacteria can alter their behaviour through chemical interactions between organisms in microbial communities - this is generally referred to as quorum sensing.

Communications blackout? Do N-acylhomoserine-lactone-degrading enzymes have any role in quorum sensing?

Microbiology, 2004
A number of bacteria, including some significant pathogens, utilize N-acylhomoserine lactones (AHLs) as quorum sensing signals. There is considerable interest in the therapeutic potential of disrupting quorum sensing. Recently, a number of bacteria have been identified which are capable of enzymic inactivation of AHLs.

Dialogues of root-colonizing biocontrol pseudomonads [PDF]

, 2018
Among biocontrol agents that are able to suppress root diseases caused by fungal pathogens, root-colonizing fluorescent pseudomonads have received particular attention because many strains of these bacteria trigger systemic resistance in host plants and ...

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]

, 2018
Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...

N-Acyl Homoserine Lactone Production by Klebsiella pneumoniae Isolated from Human Tongue Surface

Sensors, 2012
Bacteria communicate by producing quorum sensing molecules called autoinducers, which include autoinducer-1, an N-hexanoyl homoserine lactone (AHL), and autoinducer-2.
