Function
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
- ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H+ + L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate
- ATP + H2O + L-aspartyl-tRNA(Asn) + L-glutamine = ADP + 2 H+ + L-asparaginyl-tRNA(Asn) + L-glutamate + phosphate
