The present invention relates to isolated mistletoe lectin polypeptides and the
pharmaceutical composition comprising the polypeptides thereof. Also, the present
invention relates to processes for the production of mistletoe lectin polypeptides
in homologous and heterologous host systems and mistletoe lectin peptides. Further,
nucleic acid molecules are provided, which encode these mistletoe lectin polypeptides,
and also pharmaceutical compositions comprising mistletoe lectin nucleic acids.
