General annotation (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). Incorrectly charged aminoacyl-tRNA(Ala) is also edited in situ by the editing domain. HAMAP MF_00036_A

Catalytic activity

ATP + L-alanine + tRNA(Ala) = AMP + diphosphate + L-alanyl-tRNA(Ala). HAMAP MF_00036_A

Cofactor

Binds 1 zinc ion per subunit. Ref.3

Subunit structure

Homodimer. Ref.3

Subcellular location

Cytoplasm HAMAP MF_00036_A.

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 By similarity. HAMAP MF_00036_A

Sequence similarities

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