Protein attributes

Sequence length	486 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the attachment of glutamate to tRNA(Glu) in a two-step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu) By similarity.
Catalytic activity	ATP + L-glutamate + tRNA(Glu) = AMP + diphosphate + L-glutamyl-tRNA(Glu). HAMAP MF_00022
Subunit structure	Monomer By similarity.
Subcellular location	Cytoplasm. HAMAP MF_00022
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family.
