释义 [医]氨酰基转移核糖核酸合成酶,氨酰tRNA合成酶 行业词典 医学 〔EC 6.1.1〕氨酰tRNA合成酶:连接酶类中的次亚类(三级)酶,催化反应为氨酸+tRNA+ATP=氨酰tRNA+AMP+PP 1它们都是氨酸活化酶,并各对一种氨酸及该氨酸相应的tRNA具有高度特异性。各种氨酰tRNA合成酶分别以其所作用的氨酸命名,如丙氨酰tRNA合...
Based on the global helix structure as present in the crystal, it remains difficult to explain the preference of the reverse-transcriptase-associated RNAse H activity for certain sites of the template strand. Structural plasticity near the main cleavage site in suggested to govern cutting preferences...
The overall aminoacyl-tRNA synthetase reaction (A) the overall reaction. (B) Aminoacyl-tRNA formation proceeds in two steps: (Step 1) formation of an aminoacyl-adenylate and (Step 2) transfer of the activated amino acid moiety of the mixed anhydride to either the 2′-OH (class I aminoa...

Aminoacyl-tRNA synthetases Classification of aminoacyl-tRNA synthetase Although allaminoacyl-tRNAsynthetases catalyze commonenzymatic functions, they are a diverse group of proteins in terms of size andamino acidsequence. They can be divided into Class I and Class II families, each of which includesenzy...
