Serum paraoxonase/lactonase 3

Gene

Pon3

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

A phenyl acetate + H2O = a phenol + acetate.1 Publication
An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol.1 Publication
An N-acyl-L-homoserine lactone + H2O = an N-acyl-L-homoserine.1 Publication
