Characterization of the PON1 active site using modeling simulation, in relation to PON1 lactonase activity

Bioorg. Med. Chem. 16 , 7504-9, (2008)

Paraoxonase1 (PON1) is a HDL bound enzyme and many of the anti-atherogenic properties of HDL are attributed to PON1. The enzyme precise mechanism of protective action and its endogenous substrate rema...

Human paraoxonases (PON1, PON2, and PON3) are lactonases with overlapping and distinct substrate specificities.

J. Lipid Res. 46(6) , 1239-47, (2005)

The paraoxonase (PON) gene family in humans has three members, PON1, PON2, and PON3. Their physiological role(s) and natural substrates are uncertain. We developed a baculovirus-mediated expression sy...

Lactonase and lactonizing activities of human serum paraoxonase (PON1) and rabbit serum PON3.

Biochem. Pharmacol. 66(6) , 887-96, (2003)

Human paraoxonase (PON1) was previously shown to hydrolyze over 30 different lactones (cyclic esters). In the present study purified human PON1 was found to catalyze the reverse reaction (lactonizatio...
