An Intricate RNA Structure with two tRNA-derived Motifs Directs Complex Formation between Yeast Aspartyl-tRNA Synthetase and its mRNA

Accurate translation of genetic information necessitates the tuned expression of a large group of genes. Amongst them, controlled expression of the enzymes catalyzing the aminoacylation of tRNAs, the aminoacyl-tRNA synthetases, is essential to insure translational fidelity. In the yeast Saccharomyces cerevisiae, expression of aspartyl-tRNA synthetase (AspRS) is regulated in a process necessitating recognition of the 5′ extremity of AspRS...
