In enzymology a glutaminyl-tRNA synthase (glutamine-hydrolysing) (EC 6.3.5.7) is an enzyme that catalyzes the chemical reactionATP + glutamyl-tRNAGln + L-glutamine ADP + phosphate + glutaminyl-tRNAGln + L-glutamateThe 3 substrates of this enzyme are ATP glutamyl-tRNA(Gln) and L-glutamine whereas its 4 products are ADP phosphate glutaminyl-tRNA(Gln) and L-glutamate.This enzyme belongs to the family of ligases specifically those forming carbon-nitrogen bonds carbon-nitrogen ligases with glutamine as amido-N-donor.
