由mutA和mutCtRNA等位基因介导的错误翻译产生了一种强的突变子表型(H. S. Murphy和M. Z. Humayun,J. Bacteriol. 179:7507-7514,1997; M. M.斯卢普斯卡角贝卡洛夫河Lloyd和J. H.米勒,美国国家科学院院刊Acad. Sci. USA 93:4380-4385,1996)。在这里,我们表明,暴露于链霉素,抗生素已知促进误译,诱导arecA-andumuDC-独立的突变表型检测为增强诱变在3,N4-乙烯胞嘧啶病变上携带的转染M13单链DNA。
Mistranslation mediated by themutAandmutCtRNA alleles elicits a strong mutator phenotype (H. S. Murphy and M. Z. Humayun, J. Bacteriol. 179:7507–7514, 1997; M. M. Slupska, C. Baikalov, R. Lloyd, and J. H. Miller, Proc. Natl. Acad. Sci. USA 93:4380–4385, 1996). Here, we show that exposure to streptomycin, an antibiotic known to promote mistranslation, induces arecA- andumuDC-independent mutator phenotype detected as enhanced mutagenesis at a 3,N4-ethenocytosine lesion borne on transfected M13 single-stranded DNA.
