Enzyme Information

3.1.1.2
Arylesterase.
based on mapping to UniProt B5BLW5
A phenyl acetate + H(2)O = a phenol + acetate.
-!- Acts on many phenolic esters. -!- It is likely that the three forms of human paraoxonase are lactonases rather than aromatic esterases. -!- The natural substrates of the paraoxonases are lactones, with (+-)-5- hydroxy-6E,8Z,11Z,4Z-eicostetraenoic-acid 1,5-lactone being the best substrate.
3.1.8.1
Aryldialkylphosphatase.
based on mapping to UniProt B5BLW5
An aryl dialkyl phosphate + H(2)O = dialkyl phosphate + an aryl alcohol.
-!- Acts on organophosphorus compounds (such as paraoxon) including esters of phosphonic and phosphinic acids. -!- Inhibited by chelating agents. -!- Previously regarded as identical with EC 3.1.1.2.
