Comments [?]

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).
Catalytic activity	RHEA:10220: ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + H(+) + L-tyrosyl-tRNA(Tyr) EC 6.1.1.1
Subunit	Homodimer.
Subcellular location	Cytoplasm.
Similarity	Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 3 subfamily.
