In enzymology, an imidazole N-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + imidazole CoA + N-acetylimidazole Thus, the two substrates of this enzyme are acetyl-CoA and imidazole, whereas its two products are CoA and N-acetylimidazole. 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 acetyl-CoA:imidazole N-acetyltransferase. Other names in common use include imidazole acetylase, and imidazole acetyltransferase.
