Glutamate-tRNA ligase

In enzymology, a glutamate-tRNA ligase (EC number|6.1.1.17) is an enzyme that catalyzes the chemical reaction

:ATP + L-glutamate + tRNAGlu $ightleftharpoons$ AMP + diphosphate + L-glutamyl-tRNAGlu

The 3 substrates of this enzyme are ATP, L-glutamate, and tRNA(Glu), whereas its 3 products are AMP, diphosphate, and L-glutamyl-tRNA(Glu).

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-glutamate:tRNAGlu ligase (AMP-forming). Other names in common use include glutamyl-tRNA synthetase, glutamyl-transfer ribonucleate synthetase, glutamyl-transfer RNA synthetase, glutamyl-transfer ribonucleic acid synthetase, glutamate-tRNA synthetase, and glutamic acid translase. This enzyme participates in 3 metabolic pathways: glutamate metabolism, porphyrin and chlorophyll metabolism, and aminoacyl-trna biosynthesis.
