General annotation (Comments)

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 By similarity.

Catalytic activity

A phenyl acetate + H2O = a phenol + acetate.

An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol.

An N-acyl-L-homoserine lactone + H2O = an N-acyl-L-homoserine.

Cofactor

Binds 2 calcium ions per subunit By similarity.

Subunit structure

Homodimer. Interacts with CLU By similarity.

Subcellular location

Secretedextracellular space.

Tissue specificity

Plasma. Associated with HDL.

Post-translational modification

Glycosylated By similarity.

The signal sequence is not cleaved.

Miscellaneous

The preferential association of PON1 with HDL is mediated in part by its signal peptide, by binding phospholipids directly, rather than binding apo AI. The retained signal peptide may allow transfer of the protein between phospholipid surfaces By similarity.

Sequence similarities

Belongs to the paraoxonase family.
