Phosphorofluoridates nomenclature

The mechanism by which A-esterases hydrolyze organophosphates is not completely understood. Involvement of a phosphorylated active-site cysteine and displacement of an activated H20 molecule are two possible hypotheses (see Sect. 3.7.1) [56], A-Esterases comprise enzymes that hydrolyze aryl esters, paraoxon (2.2) and related organophosphate pesticides, and diisopropyl-fluorophosphate (DFP, diisopropyl phosphorofluoridate, 2.3) and related compounds, including nerve gases. These enzymes are found in the current nomenclature listed under arylesterases, aryldialkylphosphatase, and diisop-ropyl-fluorophosphatase.
