Comments [?]

case <OC:Viridiplantae>
Function Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in chloroplasts and mitochondria. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu-tRNA(Gln).
else case <OG:Organellar chromatophore>

Subcellular location Mitochondrion.
end case
case not (<OC:Viridiplantae> or <OC:Mammalia>) and not <AnyFeature:TransitM>
