| + | [https://www.uniprot.org/uniprot/SYYC_YEAST SYYC_YEAST] 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). The specificity determinants on tRNA(Tyr) are the base pair C1-G72, the discriminator residue A73, and the three anticodon bases G34, U35 and A36. Also involved in nuclear tRNA export.<ref>PMID:10588711</ref> <ref>PMID:10677221</ref> | ||
