Protein

Glutamate--tRNA ligase

Gene

gltX

Organism
Pseudomonas aeruginosa (strain ATCC 15692 / PAO1 / 1C / PRS 101 / LMG 12228)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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).UniRule annotation

Catalytic activityi

ATP + L-glutamate + tRNA(Glu) = AMP + diphosphate + L-glutamyl-tRNA(Glu).UniRule annotation

Cofactori

Zn2+UniRule annotationNote: Binds 1 zinc ion per subunit.UniRule annotation
