P83453 · SYY_THET2

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.
