Protein
Glutamyl-tRNA(Gln) amidotransferase subunit A
Organism
Saccharolobus solfataricus (strain ATCC 35092 / DSM 1617 / JCM 11322 / P2)
Function
Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln).
Similarity
Belongs to the amidase family. GatA subfamily.
