As part of an attempt to develop a semi-in vitro system of lysogenic induction, using spheroplasts of Escherichia coli K-12 lysogenic for prophage lambda, we prepared spheroplasts by depriving E. coli dap of diaminopimelic acid (DAP-spheroplasts). DAP-spheroplasts made from E. coli (lambda cI857) were thermally inducible. However, DAP-spheroplasts of E. coli (lambda) were not inducible by UV light. Thus, it appears that a functional cell wall is required for UV induction of prophage lambda.
作为开发一种溶原性诱导半体外系统尝试的一部分,我们使用携带λ原噬菌体的大肠杆菌K-12溶原菌的原生质球,通过剥夺大肠杆菌二氨基庚二酸(DAP-原生质球)来制备原生质球。由大肠杆菌(λcI857)制成的DAP-原生质球可热诱导。然而,大肠杆菌(λ)的DAP-原生质球不能被紫外线诱导。因此,看来紫外线诱导λ原噬菌体需要有功能的细胞壁。
