When Bacillus subtilis is infected by the uracil-containing DNA phage PBS2, the parental DNA labeled with radioactive uracil and cytosine remains acid insoluble. If the synthesis of the phage-induced uracil-DNA N-glycosidase inhibitor is prevented, the parental DNA is completely degraded to acid-soluble products beginning at about 6 min after infection. The host N-glycosidase probably initiates the degradation pathway, with nucleases being responsible for the remaining degradation of the DNA.
当枯草芽孢杆菌被含尿嘧啶的DNA噬菌体PBS2感染时,用放射性尿嘧啶和胞嘧啶标记的亲本DNA仍不溶于酸。如果噬菌体诱导的尿嘧啶-DNA N-糖苷酶抑制剂的合成受到抑制,亲本DNA在感染后约6分钟开始完全降解为酸溶性产物。宿主N-糖苷酶可能启动降解途径,核酸酶负责DNA的其余降解。
