Protein

Tyrosine--tRNA ligase

Gene

tyrS

Organism
Pyrococcus abyssi (strain GE5 / Orsay)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the attachment of tyrosine to tRNA(Tyr) in a two-step reaction: tyrosine is first activated by ATP to form Tyr-AMP and then transferred to the acceptor end of tRNA(Tyr).UniRule annotation

Catalytic activityi

ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + L-tyrosyl-tRNA(Tyr).UniRule annotation
