CC   -!- FUNCTION: Allows the formation of correctly charged Gln-tRNA(Gln)
CC       through the transamidation of misacylated Glu-tRNA(Gln) in chloroplasts
CC       and mitochondria. The reaction takes place in the presence of glutamine
CC       and ATP through an activated gamma-phospho-Glu-tRNA(Gln).
