The effect of ribonucleosides and deoxyribonucleosides on the phosphorolysis of 5-fluoro-2'-deoxyuridine (FUdR) was examined in cells of Escherichia coli. All nucleosides tested except guanosine and deoxyguanosine inhibited phosphorolysis. By using genetically marked strains it was found that in vivo FUdR is a specific substrate of thymidine phosphorylase.
在大肠杆菌细胞中检测了核糖核苷和脱氧核糖核苷对5-氟-2'-脱氧尿苷(FUdR)磷酸解的影响。除鸟苷和脱氧鸟苷外,所有测试的核苷均抑制磷酸解。通过使用基因标记菌株发现,体内FUdR是胸苷磷酸化酶的特异性底物。
