aminoacyl-tRNA synthetases

Also found in: Dictionary, Thesaurus.

a·mi·no·ac·yl-tRNA syn·the·tas·es

enzymes catalyzing the formation of a specific aminoacyl-tRNA from an amino acid and adenosine 5'-triphosphate with the concomitant formation of adenosine 5'-monophosphate and pyrophosphate.


transfer RNA (ribonucleic acid).

transfer RNA to which its specific amino acid has been coupled by its specific aminoacyl-tRNA synthetase.
aminoacyl-tRNA binding site
one of two tRNA binding sites on a ribosome that holds the incoming tRNA molecule charged with an amino acid. Called also A site.
aminoacyl-tRNA synthetases
a set of enzymes that couple each of the 20 amino acids to its appropriate tRNA molecule.
initiator tRNA
a special methionine tRNA that binds to the initiation codon AUG that forms part of the initiation complex at the start of mRNA translation.
peptidyl-tRNA binding site
one of two tRNA binding sites on a ribosome that holds the tRNA that is normally linked to the polypeptide chain. Called also P site.

Now that we know how AN2690 works, the same approach could be adapted to target other aminoacyl-tRNA synthetases with editing sites, which are also excellent targets for anti-microbial drugs," said Cusack, whose group performed the X-ray crystallography which revealed how AN2690 binds to LeuRS.
