Reaction: An aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol
Other name(s): organophosphate hydrolase; paraoxonase; A-esterase; aryltriphosphatase; organophosphate esterase; esterase B1; esterase E4; paraoxon esterase; pirimiphos-methyloxon esterase; OPA anhydrase (ambiguous); organophosphorus hydrolase; phosphotriesterase; paraoxon hydrolase; OPH; organophosphorus acid anhydrase
Systematic name: aryltriphosphate dialkylphosphohydrolase
Comments: Acts on organophosphorus compounds (such as paraoxon) including esters of phosphonic and phosphinic acids. Inhibited by chelating agents; requires divalent cations for activity. Previously regarded as identical with EC 18.104.22.168 arylesterase.
