Contents

Diisopropyl fluorophosphatase (DFPase), D121E mutant

Template:ABSTRACT PUBMED 20206152

Function

[DFPA_LOLVU] Biological function and substrate unknown. However, it is capable of acting on phosphorus anhydride bonds (such as phosphorus-halide and phosphorus-cyanide) in organophosphorus compounds (including nerve gases).[1]
