Function
function
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).
Miscellaneous
Although this protein is a class I aminoacyl-tRNA synthetase, it displays a class II mode of tRNA recognition.
Catalytic activity
- tRNA(Tyr) + L-tyrosine + ATP = L-tyrosyl-tRNA(Tyr) + AMP + diphosphate + H+
