Names and origin

Protein namesRecommended name:
Glutamate--tRNA ligase

EC=6.1.1.17
Alternative name(s):
Glutamyl-tRNA synthetase
Short name=GluRS
Gene names
Name:gltX
Ordered Locus Names:LGAS_0337
OrganismLactobacillus gasseri (strain ATCC 33323 / DSM 20243) [Complete proteome] [HAMAP]
Taxonomic identifier324831 [NCBI]
Taxonomic lineageBacteriaFirmicutesBacilliLactobacillalesLactobacillaceaeLactobacillus

Protein attributes

Sequence length499 AA.
Sequence statusComplete.
Protein existenceInferred 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-Rule MF_00022

Catalytic activity

ATP + L-glutamate + tRNA(Glu) = AMP + diphosphate + L-glutamyl-tRNA(Glu). HAMAP-Rule MF_00022

Subunit structure

Monomer By similarity. HAMAP-Rule MF_00022

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00022.

Sequence similarities

Belongs to the class-I aminoacyl-tRNA synthetase family.
