ATP + Glu-tRNAGln + L-glutamine
organisms lacking Gln-tRNA synthetase produce Gln-tRNAGln from misacylated Glu-tRNAGln through the transamidation activity of Glu-tRNAGln amidotransferase. The enzyme hydrolyzes Gln to Glu and NH3, using the latter product to transamidate Glu-tRNAGln in concert with ATP hydrolysis
ATP + Glu-tRNAGln + L-glutamine
the enzyme produces Gln-tRNAGln required for plastidal protein biosynthesis
ATP + Glu-tRNAGln + L-glutamine
disruption of this operon is lethal. Transamidation is the only pathway to Gln-tRNAGln in Bacillus subtilis. The enzyme furnishes a means for formation of correctly charged Gln-tRNAGln through the transamidation of misacylated Glu-tRNAGln, functionally replacing the lack of glutaminyl-tRNA synthetase activity in Gram-positive eubacteria, cyanobacteria, archaea and organelles
