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 tRNA(Ala) via its editing domain.
CC {ECO:0000255|HAMAP-Rule:MF_03134}.
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_03134};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03134};
CC Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_03134};
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_03134}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast
CC {ECO:0000269|PubMed:18431481}. Mitochondrion {ECO:0000255|HAMAP-
CC Rule:MF_03134}.
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_03134}.
CC -!- DISRUPTION PHENOTYPE: Embryo defective. Developmental arrest of the
CC embryo at early cotyledon stage. {ECO:0000305|PubMed:16297076}.
CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC {ECO:0000255|HAMAP-Rule:MF_03134}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAB10601.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
