Aspartate—tRNA ligase
In enzymology, an aspartate-tRNA ligase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are ATP, L-aspartate, and tRNA, whereas its 3 products are AMP, diphosphate, and L-aspartyl-tRNA.
This enzyme belongs to the family of ligases, to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-aspartate:tRNAAsp ligase . Other names in common use include aspartyl-tRNA synthetase, aspartyl ribonucleic synthetase, aspartyl-transfer RNA synthetase, aspartic acid translase, aspartyl-transfer ribonucleic acid synthetase, and aspartyl ribonucleate synthetase. This enzyme participates in alanine and aspartate metabolism and aminoacyl-trna biosynthesis.As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes,,,,,,,,, and.
