Protein attributes
| Sequence length | 354 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level. |
General annotation (Comments)
| Function | Hydrolyzes the toxic metabolites of a variety of organophosphorus insecticides. Capable of hydrolyzing a broad spectrum of organophosphate substrates and a number of aromatic carboxylic acid esters By similarity. |
| Catalytic activity | A phenyl acetate + H2O = a phenol + acetate. An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol. |
| Cofactor | Binds 2 calcium ions per subunit By similarity. |
| Subcellular location | Membrane; Peripheral membrane protein By similarity. |
| Post-translational modification | Glycosylated By similarity. The signal sequence is not cleaved By similarity. |
| Sequence similarities | Belongs to the paraoxonase family. |
