WebApr 12, 2024 · Covalent addition of the threonylcarbamoyl group to N(6) of adenosine 37 (t6A modification) within the anticodon loop of several tRNAs is central to the translational fidelity in all known organisms. Structures for each of the enzyme components in the Tsa (t6A) pathway from all three kingdoms of life have been determined previously. In order to … WebMar 23, 2015 · In mitochondria of Saccharomyces cerevisiae, a single aminoacyl-tRNA synthetase (aaRS), MST1, aminoacylates two isoacceptor tRNAs, tRNA1 (Thr) and tRNA2 (Thr), that harbor anticodon loops of different size and sequence. As a result of this promiscuity, reassignment of the CUN codon box from leucine to threonine is facilitated ...
