ABSTRACT:
Polypeptides comprising a polypeptide chosen from the group consisting of the polypeptide of SEQ ID No. 2 and a polypeptide exhibiting at least 90% identity with the polypeptide of SEQ ID No. 2. Polynucleotides selected from the group consisting of the polynucleotide whose sequence is between position 1538 and position 2923 of SEQ ID No. 1, and a polynucleotide encoding the polypeptide chosen from the group consisting of the polypeptide of SEQ ID No. 2 and a polypeptide exhibiting at least 90% identity with the polypeptide of SEQ ID No. 2. Furthermore, vectors and expression cassettes comprising the polynucleotide.
