cDNA as well as amino acid sequencing has revealed the complete primary structure of elongation factor EF-1 alpha from the brine shrimp Artemia. A comparison with the published sequences of bacterial EF-Tu, mitochondrial EF-Tu and chloroplastic EF-Tu shows that distinct areas of these polypeptide chains are conserved in evolution. The evolutionary distance between prokaryotic and eukaryotic types of EF-Tu is larger than among bacterial and organellar EF- Tus . A number of regions present in both EF-Tu and EF-G from Escherichia coli are also found in EF-1 alpha from Artemia.
互补脱氧核糖核酸(cDNA)以及氨基酸测序已揭示了卤虫体内延伸因子EF-1α的完整一级结构。与已发表的细菌EF-Tu、线粒体EF-Tu和叶绿体EF-Tu序列进行比较表明,这些多肽链的不同区域在进化过程中是保守的。原核生物和真核生物类型的EF-Tu之间的进化距离大于细菌和细胞器EF-Tu之间的进化距离。在大肠杆菌的EF-Tu和EF-G中都存在的一些区域,在卤虫的EF-1α中也能找到。
