Trna-synthetase
WebThe aminoacyl-tRNA synthetases are prominently known for their classic function in the first step of protein synthesis, where they bear the responsibility of setting the genetic code. Each enzyme is exquisitely adapted to covalently link a single standard amino acid to its cognate set of tRNA isoacceptors. WebMar 8, 2024 · Isoleucyl tRNA synthetase is a monomeric, class Ia aminoacyl tRNA synthetase. There are differences between bacterial and eukaryotic class Ia aaRSs in the C-terminal domain, in the C-terminal zinc finger (Znf), and in binding of mupirocin (bacterial H581 versus eukaryotic N/S; bacterial L/F581 versus eukaryotic I581) (33, 34).
