tRNA synthetase - enzyme is also named aminoacyl-tRNA synthetase (aaRSs). In the first step of protein synthesis, each enzyme can exquisitely link the respective amino acid to its cognate tRNA isoform. This diverse set of proteins is united by a common aminoacylation reaction, which attaches an amino acid to its cognate tRNA.	custom tRNA synthetase	https://integraterna.creative-biogene.com/service/custom-trna-synthetase-service.html
