Protein attributes

Sequence length	509 AA.
Sequence status	Complete.
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. HAMAP MF_00022_B
Catalytic activity	ATP + L-glutamate + tRNA(Glu) = AMP + diphosphate + L-glutamyl-tRNA(Glu). HAMAP MF_00022_B
Cofactor	Binds 1 zinc ion per subunit By similarity. HAMAP MF_00022_B
Subunit structure	Monomer By similarity. HAMAP MF_00022_B
Subcellular location	Cytoplasm HAMAP MF_00022_B.
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family.
