CC   -!- FUNCTION: Allows the formation of correctly charged Gln-tRNA(Gln)
CC       through the transamidation of misacylated Glu-tRNA(Gln) in the
CC       mitochondria. The reaction takes place in the presence of glutamine and
CC       ATP through an activated gamma-phospho-Glu-tRNA(Gln).
CC       {ECO:0000255|HAMAP-Rule:MF_03147}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H(+) +
CC         L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate;
CC         Xref=Rhea:RHEA:17521, Rhea:RHEA-COMP:9681, Rhea:RHEA-COMP:9684,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:58359,
CC         ChEBI:CHEBI:78520, ChEBI:CHEBI:78521, ChEBI:CHEBI:456216;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03147};
CC   -!- SUBUNIT: Subunit of the heterotrimeric GatCAB amidotransferase (AdT)
CC       complex, composed of A, B and C subunits. {ECO:0000255|HAMAP-
CC       Rule:MF_03147}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000255|HAMAP-Rule:MF_03147}.
CC   -!- MISCELLANEOUS: This protein may be expected to contain an N-terminal
CC       transit peptide but none has been predicted. {ECO:0000255|HAMAP-
CC       Rule:MF_03147}.
CC   -!- SIMILARITY: Belongs to the GatB/GatE family. GatB subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_03147}.
