In enzymology, a glutamine N-acyltransferase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are acyl-CoA and L-glutamine, whereas its two products are CoA and N-acyl-L-glutamine.
This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acyl-CoA:L-glutamine N-acyltransferase.
