CC   -!- FUNCTION: Catalyzes the attachment of glutamate to tRNA(Glu) in a two-
CC       step reaction: glutamate is first activated by ATP to form Glu-AMP and
CC       then transferred to the acceptor end of tRNA(Glu). {ECO:0000255|HAMAP-
CC       Rule:MF_00022}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-glutamate + tRNA(Glu) = AMP + diphosphate + L-
CC         glutamyl-tRNA(Glu); Xref=Rhea:RHEA:23540, Rhea:RHEA-COMP:9663,

CC   -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00022}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00022}.
CC   -!- SIMILARITY: Belongs to the class-I aminoacyl-tRNA synthetase family.
CC       Glutamate--tRNA ligase type 1 subfamily. {ECO:0000255|HAMAP-
CC       Rule:MF_00022}.
