The invention comprises isolated, mutant, non-wild-type organophosphorus acid anhydrolase (OPAA) enzymes having three site mutations, methods of production, and methods of use to effectively degrade organophosphorus compound EA1356 (2-methylcyclohexyl methylphosphonofluoridate) with greater catalytic efficiency than the wild-type OPAA enzyme.
本发明包括具有三个位点突变的分离、突变、非野生型有机磷酸酐分解酶(OPAA)、生产方法和使用方法,可有效降解有机磷化合物 EA1356(2-甲基环己基甲基膦酰氟),其催化效率高于野生型 OPAA 酶。
