GO:0006424:   glutamyl-tRNA aminoacylation
The process of coupling glutamate to glutamyl-tRNA, catalyzed by glutamyl-tRNA synthetase. The glutamyl-tRNA synthetase is a class-I synthetase. The activated amino acid is transferred to the 2"-OH group of a glutamic acid-accetping tRNA. The 2"-O-aminoacyl-tRNA will ultimately migrate to the 3" position via transesterification.
