Metabolite Identification

Common Name

Paraoxon

Description

Paraoxon is an acetylcholinesterase inhibitor. It is an organophosphate oxon, and the active metabolite of the insecticide parathion. It is also used as an opthamological drug against glaucoma. Paraoxon is one of the most potent acetylcholinesterase-inhibiting insecticides available, around 70% as potent as the nerve agent sarin, and so is now rarely used as an insecticide due to the risk of poisoning to humans and other animals. It is easily absorbed through skin, and was used as an assassination weapon by the apartheid-era South African chemical weapons program Project Coast.

Enzyme Details

1. Serum paraoxonase/lactonase 3

General function:: Involved in arylesterase activity
Specific function:: Has low activity towards the organophosphate paraxon and aromatic carboxylic acid esters. Rapidly hydrolyzes lactones such as statin prodrugs (e.g. lovastatin). Hydrolyzes aromatic lactones and 5- or 6-member ring lactones with aliphatic substituents but not simple lactones or those with polar substituents.
Gene Name:: PON3
Uniprot ID:: Q15166
Molecular weight:: 39607.185

Reactions

Paraoxon + Water → Diethylphosphate + 4-Nitrophenol	details

Enzyme Details

2. Serum paraoxonase/arylesterase 1

General function:: Involved in arylesterase activity
Specific function:: Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and lactones, and a number of aromatic carboxylic acid esters. Mediates an enzymatic protection of low density lipoproteins against oxidative modification and the consequent series of events leading to atheroma formation.
Gene Name:: PON1
Uniprot ID:: P27169
Molecular weight:: 39730.99

3. Serum paraoxonase/arylesterase 2

General function:: Involved in arylesterase activity
Specific function:: Capable of hydrolyzing lactones and a number of aromatic carboxylic acid esters. Has antioxidant activity. Is not associated with high density lipoprotein. Prevents LDL lipid peroxidation, reverses the oxidation of mildly oxidized LDL, and inhibits the ability of MM-LDL to induce monocyte chemotaxis.
Gene Name:: PON2
Uniprot ID:: Q15165
Molecular weight:: 39380.535
