It has been found that tRNA Phe, which was thought not to have a cytokinin in the anticodon-adjacent position due to the presence of an alternate form of modification, does contain a cytokinin or cytokinin precursor.doi:10.1016/0006-291X(70)90523-1S M Hecht...

To obtain information on the tRNA maturation process, we have developed a methodology, using NMR as a tool to monitor tRNA maturation in a non-disruptive and continuous fashion in cellular extracts. Here we report the 1H,15N chemical shift assignments of imino groups in three forms of the ...
Katunin V, Soboleva N, Mahkno V, Sedelnikova E, Zhenodarova S, Kirillov S. Effect of the nucleotide-37 on the interaction of tRNA(Phe) with the P site of Escherichia coli ribosomes. Biochimie. 1994; 76 (1):51–57.Katunin, V., Soboleva, N., Mahkno, V., Sedelnikova, E., ...
The kinetics of U-U-C-A to the dodecanucleotide (A-Cm-U-Gm-A-A-Y-A--m5C-U-Gp) isolated from the anticodon region of tRNA-Phe are similar to the kinetics of of U-U-C-A to intact tRNA-Phe. A large enhancement in constant over that predicted for U-U-C-A-U-G-A-A is obse...

【答案】：其中的(a)Phe和(b)His可能只存在一种tRNA。因为tRNAPhe的反密码子是GAA，因此它可按照摆动规则与Phe的密码子UUU和UUC配对。tRNAHis的反密码子是GUG，它可与His的密码子CAC和CAU配对。但由于Leu有六种简并密码子(UUA、UUG、CUU、CUC、CUA和CUG)，根据摆动规则，至少需要三种反密码子(UAA...
酵母苯丙氨酸tRNAphe反密码区域核苷修饰的几率和种类远超过T环和D环.在17个核苷酸的序列中,5种转录后的自然修饰在32,34,37,39和40位.为研究核苷修饰与结构和功能的关系,需建立一种研究方法和模型体系,从技术上,本方法和化学修饰核苷[1]、自动合成、色谱法纯化和定性分析[2]、热变性和热力学分析[3]、...
