Glutaminil-tRNK sintaza (glutamin-hidrolizujuća) (EC 6.3.5.7, Glu-AdT, Glu-tRNKGln amidotransferaza, glutamil-tRNKGln amidotransferaza, Glu-tRNKGln:L-glutamin amido-ligaza (formira ADP)) je enzim sa sistematskim imenom glutamil-tRNKGln:L-glutamin amido-ligaza (formira ADP).^[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju

ATP + glutamil-tRNKGln + L-glutamin ${\displaystyle \rightleftharpoons }$ ADP + fosfat + glutaminil-tRNKGln + L-glutamat

U sistemima kojima nedostaje glutamin—tRNK ligaza (EC 6.1.1.18), glutaminil-tRNKGln se formira posredstvom dva enzima.
