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-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.
