Proteases

An isolated polynucleotide encoding (i) a polypeptide comprising the amino acid sequence depicted in SEQ ID NO. 1-17, (b) a biologically active fragment of a polypeptide that comprises the amino acid sequence depicted in SEQ ID NO. 1-17, wherein the fragment has cysteine protease activity, (c) an immunogenic fragment of a polypeptide that comprises the amino acid sequence depicted in SEQ ID NO. 1-17, or (d) a polypeptide that has at least 95% sequence identity to the amino acid sequence depicted in SEQ ID NO. 1-17 and has cysteine protease activity.

An isolated polynucleotide selected from the group consisting of:

• a) a polynucleotide comprising the nucleic acid sequence depicted in SEQ ID NO. 18-34, b) a polynucleotide comprising a nucleic acid sequence that has at least 95% sequence identity to the nucleic acid sequence depicted in SEQ ID NO. 18-34, wherein the polynucleotide encodes a polypeptide that has cysteine protease activity, c) a polynucleotide complementary to a polynucleotide of a), d) a polynucleotide complementary to a polynucleotide of b), and e) an RNA equivalent of a)-d).
