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) (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H(+) +
CC         L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate;

CC   -!- SUBUNIT: Heterotrimer of A, B and C subunits. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the amidase family. GatA subfamily.
CC       {ECO:0000305}.
