Rabbit serum paraoxonase 3 (PON3) is a high density lipoprotein-associated lactonase and protects low density lipoprotein against oxidation.

D I Draganov et al.

The Journal of biological chemistry, 275(43), 33435-33442 (2000-08-10)

The paraoxonase gene family contains at least three members: PON1, PON2, and PON3. The physiological roles of the corresponding gene products are still uncertain. Until recently, only the serum paraoxonase/arylesterase (PON1) had been purified and characterized. Here we report the
