WebtRNAs bind to mRNAs inside of a protein-and-RNA structure called the ribosome. As tRNAs enter slots in the ribosome and bind to codons, their amino acids are linked to the growing polypeptide chain in a chemical reaction. The end result is a polypeptide whose amino acid sequence mirrors the sequence of codons in the mRNA. 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 …
