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 tRNA(Ala) via its editing domain.

Catalytic activity

Cofactor

Zn2+ (UniProtKB | Rhea| CHEBI:29105 )

Note: Binds 1 zinc ion per subunit.

TypeIDPosition(s)Description
Domain18-772Alanyl-transfer RNA synthetases family profile

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. Alax-L subfamily.
