| Gene name | Name=tyrS; |
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 | Reaction=tRNA(Tyr) + L-tyrosine + ATP = L-tyrosyl-tRNA(Tyr) + AMP + diphosphate + H(+); Xref=Rhea:RHEA:10220, Rhea:RHEA-COMP:9706, Rhea:RHEA-COMP:9707, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:58315, ChEBI:CHEBI:78442, ChEBI:CHEBI:78536, ChEBI:CHEBI:456215; EC=6.1.1.1; |
| SUBUNIT | Homodimer. |
| SUBCELLULAR LOCATION | Cytoplasm. |
| SIMILARITY | Belongs to the class-I aminoacyl-tRNA synthetase family. TyrS type 3 subfamily. |
