Abstract: The present invention relates to a 2227-bp DNA fragment that confers antiphage activity. Two proteins encoded by this DNA sequence are responsible for the phage resistance phenotype. When introduced in Lactococcus lactis phage-sensitive strain, this DNA fragment aborts infection of phages of the 936 and P335 species.
