abstract：:The fidelity of tRNA aminoacylation is dependent in part on amino acid editing mechanisms. A hydrolytic activity that clears mischarged tRNAs typically resides in an active site on the tRNA synthetase that is distinct from its synthetic aminoacylation active site. A second pre-transfer editing pathway that hydrolyzes ...
