The structure and function of tmRNAtmRNA has a dual function both as tRNA and mRNA and facilitates trans -translation. We made various mutation in tRNA domain of tmRNA. Our mutation studies give progressive suggestions on the structure of tmRNA.Kazuma TakadaKyoko HanawaSung Ga Lee...
tmRNA is a dual small RNA similar to a tRNA and a mRNA which plays an important role in an unusual mode of translation-trans translation. Recently, it was found that tmRNA had something to do with regulating gene expression and cell cycle. So the researchers have paid much attention on ...
A recently proposed method of RNA secondary structure prediction based on DNA sequence comparisons is reviewed and applied to several types of RNAs, including tRNA, rRNA, and mRNA. The patterns of covariation in these RNAs are analyzed based on Kimura's compensatory evolution model. The results ...
Plasmids harbouring the mutated rRNA genes were expressed and the ribosomes containing such altered RNAs were investigated for impairments in RNA-protein interaction assembly and mRNA-coded tRNA binding. 展开 关键词: ribosomal RNA Mutagenesis Protein-RNA interaction tRNA binding Subunit association ...
<正> Transfer RNA is a kind of small RNA. It has multiple functions, but the most important function is involved in protein biosynthesis. The tRNA as an adapter carrying amino acid to the proper position along the mRNA chain plays a crucial intermediate role in the process. To accomplish ...
tmRNA的结构与功能The Structure and Function of tmRNA_专业资料。tmRNA是一类具有类似tRNA分子和mRNA分子双重功能的小分子RNA,它在一种特殊的翻译模式――反式翻译模式过程中发挥重要作用。最近又发现它与基因的表达调控及细胞周期的调控等生命过程密切相关。因此,关于tmRNA的研究已经引起了研究者的高度重视,它将是RNA...

The mRNA codon in the ribosomal A-site is recognized by aminoacyl-tRNA (aa-tRNA) in a ternary complex with elongation factor Tu (EF-Tu) and GTP. Here we re... Stark,Holger,Rodnina,... - 《Nature Structural Biology》 被引量: 209发表: 2002年 Conformational Sampling of Aminoacyl-tRNA du...
Nup98/RAE1 and Nup42/Gle1/DDX19, are recruited to the vicinity using long linkers. The Nup214 complex thus localize critical factors to remove mRNA from its export factors in the final step of mRNA export.73Unlike Nup358-mediated protein export termination, this process is independent of Ran...
