Glycine N-acyltransferase
In enzymology, a glycine N-acyltransferase (GLYAT), also known as acyl-CoA:glycine N-acyltransferase (ACGNAT), (EC 2.3.1.13) is an enzyme that catalyzes the chemical reaction
- acyl-CoA + glycine CoA + N-acylglycine

Thus, the two substrates of this enzyme are acyl-CoA and glycine, whereas its two products are CoA and N-acylglycine. 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:glycine N-acyltransferase. Other names in common use include glycine acyltransferase, and glycine-N-acylase.
This enzyme plays a prominent role in converting benzoic acid (benzoate) into hippuric acid (N-benzoylglycine). Benzoic acid is metabolized by butyrate-CoA ligase into an intermediate product, benzoyl-CoA,[1] which is then metabolized by glycine N-acyltransferase into hippuric acid.[2]
