UniProtKB - Q3MGN4 (SYA_TRIV2)
Protein
Alanine--tRNA ligase
Gene
alaS
Organism
Trichormus variabilis (strain ATCC 29413 / PCC 7937) (Anabaena variabilis)
Status
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

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
