Abstract
An isolated DNA of a Lactococcus lactis showing a SEQ ID NO:1 encoding a restriction and twp modification enzymes (R/M SEQ ID NO: 2, 3 and 4). The isolated DNA is used to transform sensitive dairy cultures, such as Lactococcus lactis and Streptococcus thermophilus, to provide phage resistance. Escherichia coli can be used to produce endonucleases.
