Comments
[?]
| FUNCTION | Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl- tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp- tRNA(Asn) or phospho-Glu-tRNA(Gln). |
| CATALYTIC ACTIVITY | Reaction=L-glutamyl-tRNA(Gln) + L-glutamine + ATP + H2O = L-glutaminyl- tRNA(Gln) + L-glutamate + ADP + phosphate + H(+); Xref=Rhea:RHEA:17521, Rhea:RHEA-COMP:9681, Rhea:RHEA-COMP:9684, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:58359, ChEBI:CHEBI:78520, ChEBI:CHEBI:78521, ChEBI:CHEBI:456216; |
| CATALYTIC ACTIVITY | Reaction=L-aspartyl-tRNA(Asn) + L-glutamine + ATP + H2O = L- asparaginyl-tRNA(Asn) + L-glutamate + ADP + phosphate + 2 H(+); Xref=Rhea:RHEA:14513, Rhea:RHEA-COMP:9674, Rhea:RHEA-COMP:9677, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:58359, ChEBI:CHEBI:78515, ChEBI:CHEBI:78516, ChEBI:CHEBI:456216; |
| SUBUNIT | Heterotrimer of A, B and C subunits. |
| SIMILARITY | Belongs to the GatC family. |
