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.
摘要
在含有鼠伤寒沙门氏菌DNA限制修饰系统SA(+)和SB(+)的宿主细胞中，ocr(+)噬菌体T3和T7的复制不受影响。然而，这些噬菌体的ocr（基因0.3）突变体易受SA(+)和SB(+)系统的DNA限制和修饰作用。
