Aspartate--tRNA ligase

UniProtKB accession:  P21889

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the attachment of L-aspartate to tRNA(Asp) in a two-step reaction: L-aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp). Also mischarges tRNA(Asp) with D-aspartate, although it is a poor substrate (PubMed:10918062).
