Engineering Quorum Quenching Acylases with Improved Kinetic and Biochemical Properties
bioRxiv, 2023 Many Gram-negative bacteria respond to N-acyl-L-homoserine lactone (AHL) signals to coordinate phenotypes such as biofilm formation and virulence factor production.

Reviewing Microbial Behaviors in Ecosystems Leading to a Natural Quorum Quenching Occurrence
Brazilian Archives of Biology and Technology, 2017 Quorum sensing is considered one of the most important discoveries in cell-to-cell communication. Although revealed in Bacteria, it has been identified as well as a mechanism present in the other two domains, Eukaryota and Archaea.

Microbial Biotechnology, 2023 Virulence factor modulating (VFM) is a quorum sensing (QS) signal shared by and specific to Dickeya bacteria, regulating the production of plant cell wall degrading enzymes (PCWDEs) and virulence of Dickeya. High polarity and trace of VFM signal increase

Quorum quenching quandary: resistance to antivirulence compounds [PDF]
The ISME Journal, 2011 Abstract Quorum sensing (QS) is the regulation of gene expression in response to the concentration of small signal molecules, and its inactivation has been suggested to have great potential to attenuate microbial virulence. It is assumed that unlike antimicrobials, inhibition of QS should cause less Darwinian selection pressure for ...

Engineering quorum quenching enzymes: progress and perspectives [PDF]
Biochemical Society Transactions, 2019 Abstract Quorum sensing is a key contributor to the virulence of many important plant, animal and human pathogens. The disruption of this signalling—a process referred to as ‘quorum quenching’—is a promising new approach for controlling microbial pathogens.

Signal Disruption Leads to Changes in Bacterial Community Population
Frontiers in Microbiology, 2019 The disruption of bacterial signaling (quorum quenching) has been proven to be an innovative approach to influence the behavior of bacteria. In particular, lactonase enzymes that are capable of hydrolyzing the N-acyl homoserine lactone (AHL) molecules ...
