A class of transfer RNA separable from the majority of transfer RNA by gel electrophoresis has been observed in E. coli and in the mitochondrial fraction of HeLa cells but not in HeLa cytoplasm. The size of this class of transfer RNA, as judged by its mobility on polyacrylamide gel, is intermediate between the major part of the transfer RNA and 5S RNA. It exists in part associated with the ribosomes, and its amino acid acceptor activity is different from the major class of transfer RNA.
在大肠杆菌以及海拉细胞的线粒体组分中观察到了一类可通过凝胶电泳与大多数转移核糖核酸分离的转移核糖核酸,但在海拉细胞的细胞质中未观察到。根据其在聚丙烯酰胺凝胶上的迁移率判断,这类转移核糖核酸的大小介于转移核糖核酸的主要部分和5S核糖核酸之间。它部分与核糖体结合存在,并且其氨基酸接受活性与主要类别的转移核糖核酸不同。
