CC -!- FUNCTION: The absence of paraoxonase activity in turkey and chicken
CC blood and in turkey liver indicates that PON2, if expressed, does not
CC hydrolyze paraoxon.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a phenyl acetate + H2O = a phenol + acetate + H(+);
CC Xref=Rhea:RHEA:17309, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30089, ChEBI:CHEBI:33853, ChEBI:CHEBI:140310; EC=3.1.1.2;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl
CC alcohol.; EC=3.1.8.1;
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC Note=Binds 2 calcium ions per subunit. {ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Membrane {ECO:0000250}; Peripheral membrane
CC protein {ECO:0000250}.
CC -!- PTM: Glycosylated. {ECO:0000250}.
CC -!- PTM: The signal sequence is not cleaved. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the paraoxonase family. {ECO:0000305}.
