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:0000255|HAMAP-Rule:MF_00121}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + L-glutamine + L-glutamyl-tRNA(Gln) = ADP + H(+) +
CC         L-glutamate + L-glutaminyl-tRNA(Gln) + phosphate;
