Single amino acid changes in AspRS reveal alternative routes for expanding its tRNA repertoire in vivo
Aminoacyl-tRNA synthetases (aaRSs) are enzymes that are highly specific for their tRNA substrates. Here, we describe the expansion of a class IIb aaRS–tRNA specificity by a genetic selection that involves the use of a modified tRNA displaying an amber anticodon and the argE(amber) and lacZ(amber) re...
