Cytotoxic protein and utilization thereof

摘要

This invention relates to a new cytotoxic protein (M toxin, mucous layer devastating toxin) produced by Helicobacter pylori and the use. This invention provides a cytotoxic protein (M toxin) produced by Helicobacter pylori, a partial peptide, and an antitumor agent containing the cytotoxic protein. The protein is obtained by culturing a transformant which is transformed with a recombination vector containing DNA coding the cytotoxin protein. This invention provides further the use of the protein.
