A HELICOBACTER ANTIGEN ( gamma -GLUTAMYLTRANSFERASE) AND SEQUENCES ENCODING THE SAME

摘要

The present invention relates to a purified polynucleotide of Helicobacter characterized in that it comprises in its structure a coding sequence for a protein carrying transfer catalytic activity, for example, gamma -glutamyl residues transfer activity or its fragment or that it is capable of being hybridized with the nucleotide sequence of approximately 2kb which is inserted in the plasmid pILL308.
