CC -!- FUNCTION: Catalyzes the attachment of alanine to tRNA(Ala) in a CC two-step reaction: alanine is first activated by ATP to form Ala- CC AMP and then transferred to the acceptor end of tRNA(Ala). Also CC edits incorrectly charged Ser-tRNA(Ala) and Gly-tRNA(Ala) via its CC editing domain (By similarity). CC -!- CATALYTIC ACTIVITY: ATP + L-alanine + tRNA(Ala) = AMP + CC diphosphate + L-alanyl-tRNA(Ala). CC -!- COFACTOR: Binds 1 zinc ion per subunit (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- DOMAIN: Consists of three domains; the N-terminal catalytic CC domain, the editing domain and the C-terminal C-Ala domain. The CC editing domain removes incorrectly charged amino acids, while the CC C-Ala domain, along with tRNA(Ala), serves as a bridge to CC cooperatively bring together the editing and aminoacylation CC centers thus stimulating deacylation of misacylated tRNAs (By CC similarity). CC -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase CC family.
