phe-tRNA 释义 [医]苯丙氨酰tRNA
Aminoacyl‐tRNA synthetases (ARSs) canonical function is to conjugate specific amino acids to cognate tRNA that are required for the first step of protein synthesis. Genetic mutations that cause dysfunction or absence of ARSs result in various neurodevelopmental disorders. The human phenylalanine‐tRNA...
Based on the model, residues Lys262 and Arg305 are closer to tRNAPhe (<10 Å), while the other four residues (Cys76, Phe252, Arg401, and Thr461) have a longer distance (>15 Å) from tRNAPhe. None of these residues are directly involved in the interaction with tRNA. Download: ...

tRNAImino groupsRNA resonance assignmentPost-transcriptional modificationsTransfer RNAs (tRNAs) are heavily decorated with post-transcriptional modifications during their biosynthesis. To fulfil their functions within cells, tRNAs undergo a tightly controlled biogenesis process leading to the formation of mature...

【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...
Naturally occurring nucleoside modifications are an intrinsic feature of transfer RNA (tRNA), and have been implicated in the efficiency, as well as accuracy-of codon recognition. The structural and functional contributions of the modified nucleosides in the yeast tRNA(Phe) anticodon domain were examin...
