Protein inducing cell death of helicobacter pylori

摘要

The present invention identifies the apoptosis-inducing protein of Helicobacter pylori, analyzes the structure and provides the amino acid sequence of the protein and the nucleotide sequence encoding the amino acid sequence. Furthermore, the present invention provides inhibiting agents of an apoptosis-inducing activity of the bacterium for the treatment of disease ascribed to the bacterium and a vaccine to prevent the infection of the bacterium. ;The present invention revealed that the apoptosis-inducing protein of Helicobacter pylon is a protein complex composed by association of two kinds of proteins, which comprise a part of the amino acid sequence encoded by γ-glutamyl transferase gene (HP1118). The present invention is said protein and a vaccine comprising said protein.
