[5][6] Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid.

Because of their central role in linking amino acids with nucleotide triplets contained in tRNAs, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution.

[7] RARS (gene) has been shown to interact with QARS.
