WebRNA modifications are key regulators of RNA functions. Here, the authors identify METTL8 as the enzyme installing m3C32 in mitochondrial tRNAThr/Ser(UCN). Lack of these modifications affects tRNA structure and impairs mitochondrial translation. Published in Nature Communications ISSN 2041-1723 (Online) Publisher Nature Portfolio Country of ... WebMar 10, 2024 · The adenine (A71) at this position of tRNAThr, highly conserved from bacteria to human mitochondria, had been implicated to be important for tRNA identity and pre-tRNA processing . In addition, ~35% reduction in the level of tRNA Thr was observed in cells carrying the A15951G variant.
WebAssume a mutation in the CCA arm of tRNAThr occurs that reduces the flexibility of this region of the molecule but still allows the 3′ end of the tRNA to enter the aminoacyl-tRNA synthetase activation site. Which of the following is the MOST likely outcome? The tRNAThr may become charged with Ser but will not undergo proofreading.
