Protein attributes

Sequence length	872 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Catalytic activity	ATP + L-alanine + tRNA(Ala) = AMP + diphosphate + L-alanyl-tRNA(Ala). HAMAP MF_00036
Subcellular location	Cytoplasm. HAMAP MF_00036
Domain	The C-terminal 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.
Sequence similarities	Belongs to the class-II aminoacyl-tRNA synthetase family.
