摆动尿苷(U34)通常在所有物种中被修饰。U34修饰在后生动物中可能是必需的,但在真菌中不需要。在这篇综述中,我们提供了一个概述的类型的修改,以及它们如何影响摆动尿苷的物理化学性质。我们描述了所需的分子机制,将这些修饰引入tRNA的转录后,并讨论如何翻译后调节可能会影响的修饰酶的活性。我们强调的反密码子特异性RNA酶的活性,目标U34含有tRNA。最后,我们讨论了如何在摆动尿苷修饰缺陷导致不同物种的表型。重要的是,这篇综述将主要集中在真核生物的胞质tRNA。最近的一项综述广泛涵盖了它们的细菌和线粒体对应物。
Wobble uridines (U34) are generally modified in all species. U34 modifications can be essential in metazoans but are not required for viability in fungi. In this review, we provide an overview on the types of modifications and how they affect the physico-chemical properties of wobble uridines. We describe the molecular machinery required to introduce these modifications into tRNA posttranscriptionally and discuss how posttranslational regulation may affect the activity of the modifying enzymes. We highlight the activity of anticodon specific RNases that target U34 containing tRNA. Finally, we discuss how defects in wobble uridine modifications lead to phenotypes in different species. Importantly, this review will mainly focus on the cytoplasmic tRNAs of eukaryotes. A recent review has extensively covered their bacterial and mitochondrial counterparts.
