CC   -!- FUNCTION: Catalyzes the attachment of alanine to tRNA(Ala) in a two-
CC       step reaction: alanine is first activated by ATP to form Ala-AMP and
CC       then transferred to the acceptor end of tRNA(Ala). Also edits
CC       incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing
CC       domain. {ECO:0000255|HAMAP-Rule:MF_00036}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-alanine + tRNA(Ala) = AMP + diphosphate + L-alanyl-
CC         tRNA(Ala); Xref=Rhea:RHEA:12540, Rhea:RHEA-COMP:9657, Rhea:RHEA-
CC         COMP:9923, ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:57972,
CC         ChEBI:CHEBI:78442, ChEBI:CHEBI:78497, ChEBI:CHEBI:456215; EC=6.1.1.7;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00036};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00036};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00036};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00036}.
CC   -!- DOMAIN: Consists of three domains; the N-terminal catalytic domain, the
CC       editing domain and the C-terminal C-Ala domain. The editing domain
CC       removes incorrectly charged amino acids, while the C-Ala domain, along
CC       with tRNA(Ala), serves as a bridge to cooperatively bring together the
CC       editing and aminoacylation centers thus stimulating deacylation of
CC       misacylated tRNAs. {ECO:0000255|HAMAP-Rule:MF_00036}.
CC   -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00036}.
