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 -!- 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}.
