Background. Paraoxonase 1 (PON1) is a calcium-dependent multifunctional enzyme that binds to high-density lipoproteins. The physiological function of PON1 is related to its lactonase activity.

Low Serum Paraoxonase-1 Lactonase and Arylesterase Activities in Obese Children and Adolescents
Serum paraoxonase-1 (PON1) binds mainly to high density lipoproteins (HDLs) and protects low density lipoproteins (LDLs) against oxidation. While paraoxonase and arylesterase activities are traditionally assayed, lactonase activity, accounting for ...

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

Use of Quorum Sensing Inhibition Strategies to Control Microfouling
Interfering with the quorum sensing bacterial communication systems has been proposed as a promising strategy to control bacterial biofilm formation, a key process in biofouling development. Appropriate in vitro biofilm-forming bacteria models are needed

Reduced Serum PON1 Lactonase Activity Is Associated with Mild Cognitive Impairment and Mixed Dementia. [PDF]
High-density lipoprotein (HDL)-associated paraoxonase-1 (PON1) contributes substantially to the antioxidant and anti-inflammatory functions of HDL. Impairment of these protective properties has been associated with Alzheimer’s disease (AD) and other ...

Expression of paraoxonase 1 in HEK293 cells and its effect on lactonase and arylesterase activity in samples containing human serum and/or prooxidant or antioxidant agents - a preliminary study [PDF]
Expression of recombinant paraoxonase 1 (PON1) in the human embryonic kidney (HEK293F) cell line was evaluated. Two recombinant human PON1 proteins were investigated: PON1-Fc, which has an Fc-tag on its C-terminal, and His-PON1-Fc, which has an Fc-tag on
