Protein

Alanine--tRNA ligase

Gene

alaS

Organism
Buchnera aphidicola subsp. Schizaphis graminum (strain Sg)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

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 Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.UniRule annotation

Catalytic activityi

ATP + L-alanine + tRNA(Ala) = AMP + diphosphate + L-alanyl-tRNA(Ala).UniRule annotation

Cofactori

Binds 1 zinc ion per subunit.UniRule annotation

Family & Domainsi

Domaini

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.UniRule annotation

Sequence similaritiesi

Belongs to the class-II aminoacyl-tRNA synthetase family.UniRule annotation
