Aspartate-tRNAAsn ligase

In enzymology, an aspartate-tRNAAsn ligase (EC number|6.1.1.23) is an enzyme that catalyzes the chemical reaction

:ATP + L-aspartate + tRNAAsx $ightleftharpoons$ AMP + diphosphate + aspartyl-tRNAAsx

The 3 substrates of this enzyme are ATP, L-aspartate, and tRNAAsx, whereas its 3 products are AMP, diphosphate, and aspartyl-tRNAAsx.

This enzyme belongs to the family of ligases, specifically those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-aspartate:tRNAAsx ligase (AMP-forming). This enzyme is also called nondiscriminating aspartyl-tRNA synthetase. This enzyme participates in alanine and aspartate metabolism.
