Relationship of paraoxonase-1 and paraoxonase-3 with routine laboratory tests and oxidative stress in type 2 diabetes mellitus

Türk Biyokimya Dergisi
We aimed to investigate the relationship between serum paraoxonase-1 (PON1) and paraoxonase-3 (PON3) levels and activities with hemoglobin A1c (HbA1c), serum fasting blood glucose, lipid profile, and oxidative stress in patients with type 2 diabetes ...

Quorum Quenching Lactonase Alters Virulence of Pectobacterium atrosepticum and Reduces Maceration in Potatoes

International audiencePectobacterium atrosepticum is a soft rot phytopathogenic bacterium mainly infecting potatoes. The virulence of P. atrosepticum is controlled by quorum sensing (QS), a communication mechanism which enables bacteria to coordinate ...

Characterization of a novel N-acylhomoserine lactonase, AidP, from Antarctic Planococcus sp. [PDF]

, 2018
BACKGROUND: N-acylhomoserine lactones (AHLs) are well-studied signalling molecules produced by some Gram-negative Proteobacteria for bacterial cell-to-cell communication or quorum sensing.

Degradation of Bacterial Quorum Sensing Signaling Molecules by the Microscopic Yeast Trichosporon loubieri Isolated from Tropical Wetland Waters

Sensors, 2013
Proteobacteria produce N-acylhomoserine lactones as signaling molecules, which will bind to their cognate receptor and activate quorum sensing-mediated phenotypes in a population-dependent manner.

Negative association between paraoxonase 2, anthropometric markers and metabolic syndrome

Open Life Sciences, 2015
Background Metabolic syndrome (MS) has a great impact on cardiovascular mortality and morbidity. Our aim was to investigate the association of MS with some oxidant and antioxidant markers, including pro-and antioxidant status of peripheral blood ...

MomL, a novel marine-derived N-acyl homoserine lactonase from Muricauda olearia

, 2015
Gram-negative bacteria use N-acyl homoserine lactones (AHLs) as quorum sensing (QS) signaling molecules for interspecies communication, and AHL-dependent QS is related with virulence factor production in many bacterial pathogens.
