Background: PON1

Serum paraoxonase 1 (PON-1) is a member of the paraoxonase family which has three members: PON1, PON2, PON3.  PON-1 is a lactonase (1,2) but has significant promiscuity (2,3) that allows hydrolysis of a variety of substrates including organophosphate triesters (including many pesticides), arylesters, cyclic carbamates, glucuronides and consequently also pharmaceuticals such as statins. PON-1 is a calcium-dependent, secreted, 43 kDa protein with a 6-bladed propeller structure and an active site gorge containing a His-His catalytic dyad (4).  It is a homodimer and retains its hydrophobic signal sequence in the N-terminal region which enables its association with HDL, resulting in its localization predominantly in the plasma (5,6). Low serum PON1 and dysfunctional HDL is associated with many diseases with an inflammatory component including diabetes mellitus (7,8), rheumatoid arthritis, hepatic and renal diseases, psoriasis, and macular degeneration (9,10). PON1 shows a variety of atheroprotective properties (6,11,12) by metabolizing inflammatory lipid peroxides (13). PON-1 activity is low in coronary heart disease patients (14) and contributes to an increased risk of a major adverse cardiovascular event (15). PON-1 also protects against toxicity of organophosphorus compounds used as pesticides (16,17) thought to increase risk of neurodegenerative disorders such as Parkinson's (18) and Amyotrophic Lateral Sclerosis (19).
