Abstract

tRNA Arg II of E. coli has 77 nucleotides. There are eight minor nucleotides including inosine and 2-methyladenosine. Except for a few differences, the structure of tRNA Arg II is very similar to the structure of tRNA Arg I reported by Murao et al.3. The major difference is in the size of dihydrouridine loop. tRNA Arg II does not contain 2-thiocytosine. The unidentified nucleoside X seems to be a different modification other than nucleoside N reported to be present in tRNA Arg I.

摘要

大肠杆菌的tRNA Arg II有77个核苷酸。其中包括肌苷和2 - 甲基腺苷在内有8个稀有核苷酸。除了一些差异外，tRNA Arg II的结构与村尾等人报道的tRNA Arg I的结构非常相似。主要区别在于二氢尿嘧啶环的大小。tRNA Arg II不包含2 - 硫代胞嘧啶。未鉴定出的核苷X似乎是一种不同于据报道存在于tRNA Arg I中的核苷N的修饰。
