Fine-tuning Interaction between Aminoacyl-tRNA Synthetase and tRNA for Efficient Synthesis of Proteins Containing Unnatural Amino Acids. On the other hand, proteins were conclusively proved not to be the genetic material by Hersley and Chase in 1952 (Hershey and Chase, 1952), and the work by Rosaling Franklin, Maurice Wilkins, James Watson, and Francis Crick leading to the 1953 paper describing the three-dimensional structure of the genetic material DNA (Watson and Crick, 1953), and its double-helical structure with base-pairing according to Chargaffs rules (Chargaff, 1950). It does so by catalyzing the transesterification of a specific cognate amino acid or its precursor to one of all its compatible cognate tRNAs to form an aminoacyl-tRNA.

For example, thiolated non-proteogenic amino acids such as homocysteine and ornithine are cleared by pre-transfer editing in the active site of the enzyme by MetRS and LysRS. Enzymatic Aminoacylation of tRNA with Unnatural Amino Acids. It was discovered by George Palade in 1955 as small cytoplasmic bodies (Palade, 1955). The key advantage of chemical acylation methods is that structurally and chemically diverse groups can be added onto tRNAs without the need to re-engineer AARS. Kcat is the catalytic constant for substrate to product conversion. Generally, amino acids are recognized based on their size, functional group, and ability to bind with metal ions present in the active site of the enzyme. doi:10.1016/j.bmcl.2015.06.045, Xiao, H., Murakami, H., Suga, H., and Ferr-DAmar, A.

Aminoacyl-tRNA synthetases (AARSs) are at the center of the question of the origin of life. Post-transfer editing occurs after the transfer of amino acid to tRNA and occurs in a separate editing site. In the case of PheRS, PheRS competes for Tyr-tRNAPhe with EF-TU to recapture and edit the tRNA.
