Function
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 Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain.
Catalytic activity
- tRNA(Ala) + L-alanine + ATP = L-alanyl-tRNA(Ala) + AMP + diphosphate
Cofactor
Note: Binds 1 zinc ion per subunit.

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.
Sequence similarities
Belongs to the class-II aminoacyl-tRNA synthetase family.
