EC 3.1.8.2     
Accepted name: diisopropyl-fluorophosphatase
Reaction: diisopropyl fluorophosphate + H2O = diisopropyl phosphate + fluoride
Other name(s): DFPase; tabunase; somanase; organophosphorus acid anhydrolase; organophosphate acid anhydrase; OPA anhydrase; diisopropylphosphofluoridase; dialkylfluorophosphatase; diisopropyl phosphorofluoridate hydrolase; isopropylphosphorofluoridase; diisopropylfluorophosphonate dehalogenase
Systematic name: diisopropyl-fluorophosphate fluorohydrolase
Comments: Acts on phosphorus anhydride bonds (such as phosphorus-halide and phosphorus-cyanide) in organophosphorus compounds (including 'nerve gases'). Inhibited by chelating agents; requires divalent cations. Related to EC 3.1.8.1 aryldialkylphosphatase.
