Escherichia coli cells bearing certain mutations in rpsD (coding for the 30S ribosomal protein S4) show a ribosomal ambiguity (Ram) phenotype characterized by increased translational error rates. Here we show that spontaneous mutagenesis increases in Ram cells bearing the rpsD14 allele, suggesting that the recently described translational stress-induced mutagenesis pathway is activated in Ram cells.
在rpsD(编码30S核糖体蛋白S4)中携带某些突变的大肠杆菌细胞表现出核糖体模糊性(Ram)表型,其特征是翻译错误率增加。在这里,我们表明,携带rpsD14等位基因的Ram细胞中自发诱变增加,这表明最近描述的翻译应激诱导诱变途径在Ram细胞中被激活。
