EC 6.3.5.7;
Gene name
gatA

Comments [?]

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).
Catalytic activity RHEA:17521: ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H(+) + L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate
EC 6.3.5.7
Subunit Heterotrimer of A, B and C subunits.
Similarity Belongs to the amidase family. GatA subfamily.
