FUNCTIONCatalyzes 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 Reaction=tRNA(Ala) + L-alanine + ATP = L-alanyl-tRNA(Ala) + AMP + diphosphate; Xref=Rhea:RHEA:12540, Rhea:RHEA-COMP:9657, Rhea:RHEA- COMP:9923, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:57972, ChEBI:CHEBI:78442, ChEBI:CHEBI:78497, ChEBI:CHEBI:456215; EC=6.1.1.7;
case <FTGroup:1>
COFACTOR Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Note=Binds 1 zinc ion per subunit.;
end case
case <OC:Vertebrata>

else
SUBCELLULAR LOCATIONMitochondrion. Cytoplasm.
end case
DOMAINConsists 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.
case <OC:Mammalia>
PTMISGylated.
end case
SIMILARITYBelongs to the class-II aminoacyl-tRNA synthetase family.
