ABSTRACT:
Compositions and methods are provided for enzymatic detoxification of organophosphorus compounds. The compositions contain a recombinant enzyme expressed by a cloned gene encoding an organophosphorus acid anhydrolase (OPAA-2) from the Alteromonas sp. bacteria, strain JD6.5. These compositions may be prepared as a dry powder and reconstituted with various water sources when needed. The methods involve application of compositions of recombinant OPAA-2 to surfaces or substances contaminated with organophosphorus compounds under conditions which maximize activity and stability of the enzyme.
