An analysis of published nucleotide sequences of the 5'-untranslated region (5'-UTR) of 7 cardioviruses and 3 aphthoviruses has allowed us to derive a consensus secondary structure model that differs from that previously proposed for the 5'-UTR of entero- and rhinoviruses, though all these viruses belong to the same family, Picornaviridae. The theoretical model derived here was experimentally supported by investigating the accessibility of encephalomyocarditis virus RNA to modifications with dimethyl sulfate and its susceptibility to S1 and cobra venom nucleases. The possible involvement of the 5"-UTR secondary structure domains in the translational control is briefly discussed.
对7种心病毒和3种口蹄疫病毒的5'-非翻译区(5'-UTR)已发表的核苷酸序列进行分析后,我们得出了一个共有二级结构模型,该模型与先前针对肠道病毒和鼻病毒5'-UTR所提出的模型不同,尽管所有这些病毒都属于同一科——小核糖核酸病毒科。通过研究脑心肌炎病毒RNA对硫酸二甲酯修饰的可及性及其对S1核酸酶和眼镜蛇毒核酸酶的敏感性,本文推导的理论模型得到了实验支持。文中还简要讨论了5'-UTR二级结构域在翻译控制中的可能作用。
