Protein attributes

Sequence length	399 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

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. HAMAP MF_02007
Catalytic activity	ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + L-tyrosyl-tRNA(Tyr). HAMAP MF_02007
Subunit structure	Homodimer By similarity. HAMAP MF_02007
Subcellular location	Cytoplasm By similarity HAMAP MF_02007.
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 2 subfamily. Contains 1 S4 RNA-binding domain.
