WebApr 12, 2024 · Introduction. Aminoacyl-tRNA synthetases (aaRSs) are ubiquitously expressed housekeeping proteins that are critical for catalyzing the ligation of tRNAs with cognate amino acids, thus providing the aminoacyl-tRNA building blocks for ribosomal protein synthesis (1, 2).In addition to tRNA aminoacylation, approximately one-half of …

WebDec 12, 2024 · tRNA is a key component in life’s most fundamental process, the translation of the instructions contained in mRNA into proteins. Its role had to be executed as soon as the earliest translation emerged, but the questions of the prebiotic tRNA materialization, aminoacylation, and the origin of the coding triplets it carries are still open. WebKinetics of tRNA folding monitored by aminoacylation We describe a strategy for tracking Mg²⁺-initiated folding of ³²P-labeled tRNA molecules to their native structures based on the capacity for aminoacylation by the cognate aminoacyl-tRNA synthetase enzyme. barbara ware jazz singer

WebtRNA synthetases catalyze the ligation of tRNAs to their cognate amino acids in an ATP-dependent manner. The reaction proceeds in two steps. First, amino acid and ATP form … WebNov 27, 2024 · Aminoacyl-tRNA synthetases (ARSs) catalyze the ligation of amino acids to their cognate transfer RNAs (tRNAs), thus playing an important role in protein synthesis. In eukaryotic cells, these enzymes exist in free form or in the form of multi-tRNA synthetase complex (MSC). WebDec 20, 2024 · Abstract. Transfer RNA (tRNA) utilizes multiple properties of abundance, modification, and aminoacylation in translational regulation. These properties were typically studied one-by-one; however, recent advance in high throughput tRNA sequencing enables their simultaneous assessment in the same sequencing data. barbara waterhouse
