3.1.8.1 | an aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol |
acts on organophosphorous compounds, such as paraoxon, including esters of phosphonic acid and phosphinic acids. Inhibited by chelating agents, requires divalent cations for activity. Previously regarded as identical with EC 3.1.1.2 arylesterase |

3.1.8.1 | an aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol |
catalytic reaction mechanism involving residue Asp269, and role of Asp270 for the catalytic function, molecular dynamics and modelling, overview. The reaction is supposed to proceed by a two-step addition-elimination (An + Dn) mechanism, which goes through a common pentavalent intermediate observed in phosphoryl transfer reactions. The first step is the activation of H2O by Asp269 and Glu53 to form a nucleophile hydroxide and a metastable pentavalent complex. Both the residues Asn168 and Asn224 help the leaving group leave through hydrogen bonds |

3.1.8.1 | an aryl dialkyl phosphate + H2O = dialkyl phosphate + an aryl alcohol |
catalytic reaction with orpanophosphonates starts with cleavageof the P-O bond. Reaction proceeds through a displacement mechanism and generates a chiral product in situ with an inversion of stereochemical configuration at the phosphorous atom |
