Aspartate--tRNA(Asp/Asn) ligase

UniProtKB accession:  Q51422

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Aspartyl-tRNA synthetase with relaxed tRNA specificity since it is able to aspartylate not only its cognate tRNA(Asp) but also tRNA(Asn). Is 1.5 times more efficient at aminoacylating E.coli tRNA(Asp) over tRNA(Asn). Reaction proceeds in two steps: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp/Asn).
