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). |
| CATALYTIC ACTIVITY | Reaction=ATP + L-glutamate + tRNA(Glu) = AMP + diphosphate + L- glutamyl-tRNA(Glu); Xref=Rhea:RHEA:23540, Rhea:RHEA-COMP:9663, Rhea:RHEA-COMP:9680, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:78442, ChEBI:CHEBI:78520, ChEBI:CHEBI:456215; EC=6.1.1.17; |
| case <FTGroup:1> | |
| COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Note=Binds 1 zinc ion per subunit.; |
| end case | |
| SUBUNIT | Monomer. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| SIMILARITY | Belongs to the class-I aminoacyl-tRNA synthetase family. Glutamate--tRNA ligase type 1 subfamily. |
