CC -!- FUNCTION: Allows the formation of correctly charged Gln-tRNA(Gln)
CC through the transamidation of misacylated Glu-tRNA(Gln) in organisms
CC which lack glutaminyl-tRNA synthetase. The reaction takes place in the
CC presence of glutamine and ATP through an activated gamma-phospho-Glu-
CC tRNA(Gln). {ECO:0000255|HAMAP-Rule:MF_00120}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H(+) +
CC L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate;

CC ChEBI:CHEBI:78520, ChEBI:CHEBI:78521, ChEBI:CHEBI:456216; EC=6.3.5.7;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00120};
CC -!- SUBUNIT: Heterotrimer of A, B and C subunits. {ECO:0000255|HAMAP-
CC Rule:MF_00120}.
CC -!- SIMILARITY: Belongs to the amidase family. GatA subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00120}.
