Protein attributes

Sequence length	528 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (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) By similarity.
Catalytic activity	ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + L-tyrosyl-tRNA(Tyr).
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family. Contains 1 tRNA-binding domain.
