Dfpase enzymes from aplysia californica

An isolated polypeptide having organophosphorous hydrolase activity, selected from the group consisting of:

• (a) a polypeptide comprising an amino acid sequence having at least 75%, more preferably at least 80%, even more preferably at least 85%, most preferably at least 90%, and even most preferably at least 95% identity to the mature polypeptide of SEQ ID NO:
• 2;
• (b) a polypeptide encoded by a polynucleotide that hybridizes under at least medium-high stringency conditions with (i) the mature polypeptide coding sequence of SEQ ID NO:
• 1, (ii) a DNA sequence comprising the mature polypeptide coding sequence of SEQ ID NO:
• 1, or (iii) a full-length complementary strand of (i) or (ii);
• (c) a polypeptide encoded by a polynucleotide comprising a nucleotide sequence having at least 65%, more preferably at least 70%, more preferably at least 75%, more preferably at least 80%, more preferably at least 85%, more preferably at least 90%, more preferably at least 95%, more preferably at least 96%, even more preferably at least 97%, most preferably at least 98% and even most preferably 99% identity to the mature polypeptide coding sequence of SEQ ID NO:
• 1;
• (d) a variant comprising a substitution, deletion, and/or insertion of one or more (several) amino acids of the mature polypeptide of SEQ ID NO:
• 2.
