Quorum sensing negatively regulates multinucleate cell formation during intracellular growth of Burkholderia pseudomallei in macrophage-like cells. [PDF]
PLoS ONE, 2013 Burkholderia pseudomallei is a Gram-negative environmental bacterium and the causative agent of melioidosis, a potentially fatal, acute or chronic disease endemic in the tropics.

Regulation of AHL Production and Its Contribution to Epiphytic Fitness in Pseudomonas syringae
Molecular Plant-Microbe Interactions, 2004 Pseudomonas syringae forms large cell aggregates that are more stress tolerant than solitary cells during epiphytic growth on plants. The differential survival of aggregates on leaves suggests that epiphytic fitness traits may be controlled in a density ...

The Role of SprIR Quorum Sensing System in the Regulation of Serratia proteamaculans 94 Invasion
Microorganisms, 2021 The bacteria Serratia proteamaculans 94 have a LuxI/LuxR type QS system consisting of AHL synthase SprI and the regulatory receptor SprR. We have previously shown that inactivation of the AHL synthase sprI gene resulted in an increase in the invasive ...

The fitness burden imposed by synthesising quorum sensing signals [PDF]
, 2016 It is now well established that bacterial populations utilize cell-to-cell signaling (quorum-sensing, QS) to control the production of public goods and other co-operative behaviours.

Genome sequencing-assisted identification and the first functional validation of N-acyl-homoserine-lactone synthases from the Sphingomonadaceae family [PDF]
PeerJ, 2016 Background Members of the genus Novosphingobium have been isolated from a variety of environmental niches. Although genomics analyses have suggested the presence of genes associated with quorum sensing signal production e.g., the N-acyl-homoserine ...

Proton translocation in proteins [PDF]
, 1989 The active transport of protons across the low dielectric barrier imposed by biological membranes is accomplished by a plethora of proteins that span the ca. 40 Å of the phospholipid bilayer.

Front-propagation in bacterial inter-colony communication
, 2018 Many bacterial species exchange signaling molecules to coordinate population-wide responses. For this process known as quorum sensing the concentration of the respective molecules is crucial. Here we consider the interaction between spatially distributed

The quorum quenching enzyme Aii20J modifies in vitro periodontal biofilm formation
Frontiers in Cellular and Infection Microbiology, 2023 IntroductionRecent studies have revealed the presence of N-acyl-homoserine lactones (AHLs) quorum sensing (QS) signals in the oral environment. Yet, their role in oral biofilm development remains scarcely investigated.
