Structural and Biochemical Characterization of AidC, a Quorum-Quenching Lactonase With Atypical Selectivity [PDF]

open access: yes, 2015
Quorum-quenching catalysts are of interest for potential application as biochemical tools for interrogating interbacterial communication pathways, as antibiofouling agents, and as anti-infective agents in plants and animals.

AhlX, an N-acylhomoserine Lactonase with Unique Properties [PDF]

open access: yesMarine Drugs, 2019
N-Acylhomoserine lactonase degrades the lactone ring of N-acylhomoserine lactones (AHLs) and has been widely suggested as a promising candidate for use in bacterial disease control. While a number of AHL lactonases have been characterized, none of them has been developed as a commercially available enzymatic product for in vitro AHL quenching due to ...

Modulation of paraoxonase 1 and 3 expression after moderate exercise training in the rat

open access: yesJournal of Lipid Research, 2009
Paraoxonases (PONs) are a small family of antioxidant enzymes whose antiatherogenic activity is well known. The aim of the present study was the evaluation of the effects of moderate aerobic training on their expression using a rat model.

\u3cem\u3eArabidopsis thaliana\u3c/em\u3e GLX2-1 Contains a Dinuclear Metal Binding Site, but Is Not a Glyoxalase 2 [PDF]

open access: yes, 2009
In an effort to probe the structure and function of a predicted mitochondrial glyoxalase 2, GLX2-1, from Arabidopsis thaliana, GLX2-1 was cloned, overexpressed, purified and characterized using metal analyses, kinetics, and UV–visible, EPR, and 1H-NMR ...

Evidence for Complex Interplay between Quorum Sensing and Antibiotic Resistance in Pseudomonas aeruginosa

open access: yesMicrobiology Spectrum, 2022
Quorum sensing (QS) is a cell-density-dependent, intercellular communication system mediated by small diffusible signaling molecules. QS regulates a range of bacterial behaviors, including biofilm formation, virulence, drug resistance mechanisms, and ...

The symbiotic biofilm of Sinorhizobium fredii SMH12, necessary for successful colonization and symbiosis of glycine max cv osumi, is regulated by quorum sensing systems and inducing Flavonoids via NodD1 [PDF]

open access: yes, 2014
Bacterial surface components, especially exopolysaccharides, in combination with bacterial Quorum Sensing signals are crucial for the formation of biofilms in most species studied so far.

Effects of Signal Disruption Depends on the Substrate Preference of the Lactonase

open access: yesFrontiers in Microbiology, 2020
Many bacteria produce and use extracellular signaling molecules such as acyl homoserine lactones (AHLs) to communicate and coordinate behavior in a cell-density dependent manner, via a communication system called quorum sensing (QS).

Biotechnological applications of functional metagenomics in the food and pharmaceutical industries [PDF]

open access: yes, 2015
peer-reviewedMicroorganisms are found throughout nature, thriving in a vast range of environmental conditions. The majority of them are unculturable or difficult to culture by traditional methods.

Differential active site loop conformations mediate promiscuous activities in the lactonase SsoPox.

open access: yesPLoS ONE, 2013
Enzymes are proficient catalysts that enable fast rates of Michaelis-complex formation, the chemical step and products release. These different steps may require different conformational states of the active site that have distinct binding properties ...
