Reaction
diisopropyl fluorophosphate + H2O = diisopropyl phosphate + fluoride
Other name(s)
DFPase,
tabunase,
somanase,
organophosphorus acid anhydrolase,
organophosphate acid anhydrase,
OPA anhydrase (ambiguous),
diisopropylphosphofluoridase,
dialkylfluorophosphatase,
diisopropyl phosphorofluoridate hydrolase,
isopropylphosphorofluoridase,
diisopropylfluorophosphonate dehalogenase
Systematic name
diisopropyl-fluorophosphate fluorohydrolase
CAS registry number
9032-18-2
Comment
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.
