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.
