- Aspartate-tRNA ligase
enzymology, an aspartate-tRNA ligase (EC number|18.104.22.168) is an enzymethat catalyzes the chemical reaction
:ATP + L-aspartate + tRNAAsp AMP + diphosphate + L-aspartyl-tRNAAsp
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:tRNAAsp ligase (AMP-forming). 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 metabolismand aminoacyl-trna biosynthesis.
As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes PDB link|1ASY, PDB link|1ASZ, PDB link|1B8A, PDB link|1C0A, PDB link|1EFW, PDB link|1EOV, PDB link|1EQR, PDB link|1G51, PDB link|1IL2, and PDB link|1L0W.
CAS registry numberfor this enzyme class is CAS registry|9027-32-1."
