Protein

Glutamate--tRNA ligase

Gene

gltX

Organism
Idiomarina loihiensis (strain ATCC BAA-735 / DSM 15497 / L2-TR)
Status
Reviewed-Annotation score: -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
