Protein attributes

Sequence length	430 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_02006
Catalytic activity	ATP + L-tyrosine + tRNA(Tyr) = AMP + diphosphate + L-tyrosyl-tRNA(Tyr). HAMAP MF_02006
Subunit structure	Homodimer By similarity. HAMAP MF_02006
Subcellular location	Cytoplasm By similarity HAMAP MF_02006.
Sequence similarities	Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 1 subfamily. Contains 1 S4 RNA-binding domain.
