Beschreibung
Zusammenfassung:	The present invention provides an isolated DNA molecule encoding Malathion Carboxylesterase capable of hydrolysing at least one organophosphate selected from the group consisting of carboxylester organophosphates and dimethyloxon organophosphates. The DNA molecule comprises a nucleotide sequence having at least 60%, preferably at least 80% and more preferably at least 95% homology with Lc?E 7, in which the protein encoded by the DNA molecule differs from E 3 at least in the substitution of Trip at position 251 with an amino acid selected from the group consisting of Leu, Ser, Ala, Ile, Val, Thr, Cys, Met and Gly. The preferred substituents are Leu and Ser.
