ISOLATED PHOSPHOTRIESTERASE POLYPEPTIDES, POLYNUCLEOTIDES ENCODING SAME AND USES THEREOF IN TREATING OR PREVENTING ORGANOPHOSPHATE EXPOSURE ASSOCIATED DAMAGE

摘要

A genetically modified polypeptide is disclosed which comprises an amino acid sequence of phosphotriesterase (PTE) having at least twice the catalytic efficiency for a V-type nerve agent as a polypeptide which consists of the sequence as set forth in SEQ ID NO: 1, when assayed under identical conditions.
