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 and the consequent series of events leading to atheroma formation. Ref.18 Ref.20
Catalytic activity	A phenyl acetate + H2O = a phenol + acetate. Ref.3 Ref.15 Ref.16 Ref.20 Ref.24 An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol. Ref.3 Ref.15 Ref.16 Ref.20 Ref.24 An N-acyl-L-homoserine lactone + H2O = an N-acyl-L-homoserine. Ref.3 Ref.15 Ref.16 Ref.20 Ref.24
Cofactor	Binds 2 calcium ions per subunit.
Subunit structure	Homodimer. Heterooligomer with phosphate-binding protein (HPBP). Interacts with CLU. Ref.14 Ref.20 Ref.22
Subcellular location	Secreted › extracellular space.
Tissue specificity	Plasma, associated with HDL (at protein level). Expressed in liver, but not in heart, brain, placenta, lung, skeletal muscle, kidney or pancreas. Ref.13 Ref.14
Post-translational modification	Glycosylated. Ref.19 Ref.21 Ref.23 The signal sequence is not cleaved. Present in two forms, form B contains a disulfide bond, form A does not.
Polymorphism	The allelic form of the enzyme with Gln-192 (allozyme A) hydrolyzes paraoxon with a low turnover number and the one with Arg-192 (allozyme B) with a high turnover number.
Involvement in disease	Genetic variation in PON1 is associated with susceptibility to microvascular complications of diabetes type 5 (MVCD5) [MIM:612633]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis. Note=Homozygosity for the Leu-54 allele is strongly associated with the development of retinal disease in diabetic patients.
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.
Sequence similarities	Belongs to the paraoxonase family.
