PG - 366-75 LID - 10.1016/j.febslet.2009.11.045 [doi] AB - During protein synthesis, tRNA serves as the intermediary between cognate amino acids and their corresponding RNA trinucleotide codons. Aminoacyl-tRNA is also a biosynthetic precursor and amino acid donor for other macromolecules. AA-tRNAs allow transformations of acidic amino acids into their amide-containing counterparts, and seryl-tRNA(Ser) donates serine for antibiotic synthesis. Aminoacyl-tRNA is also used to cross-link peptidoglycan, to lysinylate the lipid bilayer, and to allow proteolytic turnover via the N-end rule. These alternative functions may signal the use of RNA in early evolution as both a biological scaffold and a catalyst to achieve a wide variety of chemical transformations.
