CLONING DNA FRAGMENTS ENCODING A BACTERIOPHAGE RESISTANCE MECHANISM

摘要

DNA fragments coding for a mechanism capable of resistance to abortive infection mechanism type (Abi-type) bacteriophages. These fragments can be obtained by cloning the chromosomal or plasmid DNA of a bacteriophage-resistant lactic bacteria strain. Also described are polypeptides involved in the Abi-type resistance mechanism, coded by said fragments. The invention further concerns recombinant vectors and transformed bacterial strains comprising said DNA fragments.
