WebAn aminoacyl-tRNA synthetase ( aaRS or ARS ), also called tRNA-ligase, is an enzyme that attaches the appropriate amino acid onto its corresponding tRNA. 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. WebMay 5, 2024 · Because the factors involved in mRNA capping and polyadenylation are physically associated with RNA polymerase II and not RNA polymerase III, tRNAs do not undergo capping and polyadenylation like mRNAs. tRNAs, however do undergo extensive post-transcriptional processing to get them into their final form.
