(1994). KM and Kcat values of amino acids for AARS from E. coli unless mentioned otherwise. For instance, it is well established that AARSs are also involved in mRNA binding and regulation in yeast (Levi and Arava, 2019), and AARSs can autoregulate their own expression by binding to specific DNA in bacteria (Putney and Schimmel, 1981). Upon initial binding, specific interactions between tRNA and AARS ensure recognition of the correct tRNA. Currently, a more sophisticated one-pot method for in vitro tRNA synthesis has been developed (Korenci, Sll, and Ambrogelly, 2002). AARSs can be engineered by modifying the amino acid binding pocket, tRNA binding pocket, and editing domain for acylating NC-AAs onto tRNAs. One of the least commonly used isoacceptor tRNAs is generally used for codon reassignment.
