Abstract
The invention concerns polypeptides constituting subunits of a resistance mechanism to Ic type R/M bacteriophages, active against the phages of lactic acid bacteria, and nucleic acid sequences coding for said polypeptides. The expression of said polypeptides in lactic acid bacteria enables to increase resistance to the attacks of bacteriophages.
Claims12
Polypeptide which constitutes one of the HsdR, HsdM, or HsdS subunits of a mechanism of resistance to type Ic R/M bacteriophages, characterized in that said mechanism is active against the phages of lactic acid bacteria.
