CC -!- FUNCTION: Allows the formation of correctly charged Asn-tRNA(Asn) or
CC Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn)
CC or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl-
CC tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the
CC presence of glutamine and ATP through an activated phospho-Asp-
CC tRNA(Asn) or phospho-Glu-tRNA(Gln). {ECO:0000256|ARBA:ARBA00024799}.
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:0000256|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:78520, ChEBI:CHEBI:78521, ChEBI:CHEBI:456216;
CC Evidence={ECO:0000256|ARBA:ARBA00000924, ECO:0000256|HAMAP-
CC Rule:MF_03147};
CC -!- SUBUNIT: Heterotrimer of A, B and C subunits.
CC {ECO:0000256|ARBA:ARBA00011123}.
CC -!- SUBUNIT: Subunit of the heterotrimeric GatCAB amidotransferase (AdT)
CC complex, composed of A, B and C subunits. {ECO:0000256|HAMAP-
CC Rule:MF_03147}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000256|HAMAP-Rule:MF_03147}.
CC -!- SIMILARITY: Belongs to the GatB/GatE family. GatB subfamily.
CC {ECO:0000256|ARBA:ARBA00005306, ECO:0000256|HAMAP-Rule:MF_03147}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
