ACL_RS04480

Uniprot: A9NGN9
Description: alanine--tRNA ligase
EC number: 6.1.1.7
Annotation score: 3 out of 5
Miscellaneous [CC]:
Protein existence: Inferred from homology
Catalytic activity: CATALYTIC ACTIVITY: ATP + L-alanine + tRNA(Ala) = AMP + diphosphate + L-alanyl-tRNA(Ala). {ECO:0000255|HAMAP-Rule:MF_00036}.
Cofactor: COFACTOR: Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP-Rule:MF_00036}; ; Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00036}
Enzyme regulation:
Function [CC]: FUNCTION: Catalyzes 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 Ser-tRNA(Ala) and Gly-tRNA(Ala) via its editing domain. {ECO:0000255|HAMAP-Rule:MF_00036}.

Chain: CHAIN 1 851 Alanine--tRNA ligase. /FTId=PRO_0000347467.
Signal peptide:
Domain [CC]: DOMAIN: Consists 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. {ECO:0000255|HAMAP-Rule:MF_00036}.
Sequence similarities: SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family. {ECO:0000255|HAMAP-Rule:MF_00036}.
Protein families: Class-II aminoacyl-tRNA synthetase family
