Comments
[?]
| FUNCTION | Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged tRNA(Ala) via its editing domain. |
| CATALYTIC ACTIVITY | Reaction=ATP + L-alanine + tRNA(Ala) = AMP + diphosphate + L-alanyl- tRNA(Ala); Xref=Rhea:RHEA:12540, Rhea:RHEA-COMP:9657, Rhea:RHEA- COMP:9923, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:57972, ChEBI:CHEBI:78442, ChEBI:CHEBI:78497, ChEBI:CHEBI:456215; EC=6.1.1.7; |
| COFACTOR | Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Note=Binds 1 zinc ion per subunit.; |
| SUBUNIT | Monomer. |
| SUBCELLULAR LOCATION | Plastid, chloroplast. Mitochondrion. |
| DOMAIN | Consists of three domains; the N-terminal catalytic domain, the editing domain and the C-terminal C-Ala domain. The editing domain removes incorrectly charged amino acids, while the C-Ala domain, along with tRNA(Ala), serves as a bridge to cooperatively bring together the editing and aminoacylation centers thus stimulating deacylation of misacylated tRNAs. |
| SIMILARITY | Belongs to the class-II aminoacyl-tRNA synthetase family. |
