为了开发抑制性tRNA项目,Tevard获得了Christopher Ahern教授及其前博士后John Lueck 2019年1篇论文相关的知识产权的授权[2],Ahern教授和Lueck建立了一个包含数百个ACE-tRNAs(anticodon-edited tRNAs,反密码子编辑的tRNAs)的文库,每一个ACE-tRNA都能抑制过早终止密码...
④ 有一个反密码子环,在这一环的顶端有三个暴露的碱基,称为反密码子(anticodon)。反密码子可以与mRNA链上互补的密码子配对。 ⑤ 有一个胸腺嘧啶环。 rRNA 核糖体是由数种蛋白和核糖体RNA组成的。以前,人们设想核糖体蛋白可能是核糖体的功能部分,而且核糖体RNA的作用是作为大的结构支撑核糖体。然而,现在已经清...
氨酰tRNA分子中的反向互补序列,称为抗基序列(anticodon),与核糖体上的相应互补序列相结合。这种互补配对确保正确的氨酰tRNA与核糖体结合,以便在蛋白质合成过程中向多肽链中加入正确的氨酸。 另外,核糖体还依赖于tRNA上的特定修饰,以识别和选择氨酰tRNA。几种tRNA修饰的位置在氨酰tRNA中是高度保守的,这些修饰增加了...

This tRNA possesses a quasi-complementary anticodon (GUC) and crystal studies showed that the molecules are packed in the crystalline lattice in a way involving anticodon-anticodon interactions of the Watson-Crick type. Considering the existence of conformational differences between the structure of tRNA...
Subclass IIb aminoacyl-tRNA synthetases (Asn-, Asp- and LysRS) recog nize the anticodon triplet of their cognate tRNA (GUU, GUC and UUU, respectively) through an OB-folded N-terminal extension. In the present study, the specificity of constitutive lysyl-tRNA synthetase (LysS) from Escherichia...
