Abstract

In host cells containing the Salmonella typhimurium DNA restriction-modification systems SA(+) and SB(+), replication of the ocr(+) bacteriophages T3 and T7 is not impaired. However, ocr (gene 0.3) mutants of these phages are susceptible to DNA restriction and modification by the SA(+) and SB(+) systems.
