Escherichia coli K-12 substr. MG1655 Gene-Ontology-Terms Class: GO:0004812 - aminoacyl-tRNA ligase activity

Synonyms: GO:0017100, aminoacyl-tRNA synthetase activity

Definition: Catalysis of the formation of aminoacyl-tRNA from ATP, amino acid, and tRNA with the release of diphosphate and AMP.

Summary:
Note that the bond resulting from this reaction is a carboxylic acid ester bond, linking the alpha carboxyl group of the amino acid to either the 2' or 3' hydroxyl of the 3'- terminal adenyl residue of the tRNA.
