2dlc is a 2 chain structure with sequence from Atcc 18824. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
[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.[1][2]
