Protein name |
RecName:
|
Full=Aspartyl/glutamyl-tRNA(Asn/Gln) amidotransferase subunit C;
|
|
Short=Asp/Glu-ADT subunit C;
|
|
EC 6.3.5.-;
|
|
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 |
RHEA:17521: ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H(+) + L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate
|
|
RHEA:14513: ATP + H2O + L-aspartyl-tRNA(Asn) + L-glutamine = ADP + 2 H(+) + L-asparaginyl-tRNA(Asn) + L-glutamate + phosphate
|
Subunit |
Heterotrimer of A, B and C subunits. |
Similarity |
Belongs to the GatC family. |
GO:0050567; Molecular function: glutaminyl-tRNA synthase (glutamine-hydrolyzing) activity.
GO:0006412; Biological process: translation.
