Protein
Bifunctional glutamate/proline--tRNA ligase
Organism

Function
Catalyzes the attachment of the cognate amino acid to the corresponding tRNA in a two-step reaction: the amino acid is first activated by ATP to form a covalent intermediate with AMP and is then transferred to the acceptor end of the cognate tRNA.
Similarity
In the C-terminal section; belongs to the class-II aminoacyl-tRNA synthetase family.
