CC -!- FUNCTION: Hydrolyzes the toxic metabolites of a variety of CC organophosphorus insecticides. Capable of hydrolyzing a broad CC spectrum of organophosphate substrates and lactones, and a number CC of aromatic carboxylic acid esters. Mediates an enzymatic CC protection of low density lipoproteins against oxidative CC modification. {ECO:0000250|UniProtKB:P27169}. CC -!- CATALYTIC ACTIVITY: A phenyl acetate + H(2)O = a phenol + acetate. CC {ECO:0000250|UniProtKB:P27169}. CC -!- CATALYTIC ACTIVITY: An aryl dialkyl phosphate + H(2)O = dialkyl CC phosphate + an aryl alcohol. {ECO:0000250|UniProtKB:P27169}. CC -!- CATALYTIC ACTIVITY: An N-acyl-L-homoserine lactone + H(2)O = an N- CC acyl-L-homoserine. {ECO:0000250|UniProtKB:P27169}. CC -!- COFACTOR: CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250}; CC Note=Binds 2 calcium ions per subunit. {ECO:0000250}; CC -!- SUBUNIT: Homodimer. Interacts with CLU. CC {ECO:0000250|UniProtKB:P27169}. CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space. CC -!- TISSUE SPECIFICITY: Plasma. Associated with HDL. CC -!- PTM: Glycosylated. {ECO:0000250|UniProtKB:P27169}. CC -!- PTM: The signal sequence is not cleaved. CC -!- MISCELLANEOUS: The preferential association of PON1 with HDL is CC mediated in part by its signal peptide, by binding phospholipids CC directly, rather than binding apo AI. The retained signal peptide CC may allow transfer of the protein between phospholipid surfaces. CC {ECO:0000250|UniProtKB:P27169}. CC -!- SIMILARITY: Belongs to the paraoxonase family. {ECO:0000305}.
