The aforementioned approaches were used for incorporating modified or non-canonical amino acids (NC-AAs). GCE involves the increase in the genetic code alphabet by introducing new base nucleotides (Hoshika et al., 2019), unnatural base pairs (UBPs) (Mukba et al., 2020), creating new codons, and increasing the codon size to 4 (quadruplet codon) (Hohsaka et al., 2001).

In vitro synthesis of functional tRNA has made it easier to study interactions of tRNA with other components such as mRNA (Fauzi, Jack, and Hines, 2005) and AARSs (Wang et al., 2015), to investigate tRNA stability in vitro (Serebrov et al., 1998), and to determine mutational effects on tRNA function (Tamura et al., 1992).

However, similar to the chemoenzymatic method, this method is laborious, technically demanding, and suffers from poor efficiency due to cyclic-tRNA by-product which inhibits protein synthesis, and also the short lifetime of aminoacylated tRNA (Yamanaka et al., 2004). According to this model, the active site of the enzyme acts as a first coarse sieve to filter out amino acids that are larger than the cognate amino acid. Nucl. The .gov means its official. Sci.

HGT from ancient lineages that diverge before LUCA into the ancestors of, MeSH There is a nucleotide-based world (DNA and RNA) and an amino acidbased world (proteins). A classic example is the requirement of template RNA for amino acid incorporation during protein synthesis which was proved in vitro by Nirenberg in 1961 using a cell-free system extracted from E. coli (Nirenberg and Matthaei, 1961). In general, for the amino acid activation step, tRNA is not required but some AARSs such as GlnRS, GluRS, ArgRS, and class I LysRS require tRNA as a prerequisite for amino acid activation.
