In enzymology, a glucosamine N-acetyltransferase (EC 2.3.1.3) is an enzyme that catalyzes the chemical reaction

acetyl-CoA + D-glucosamine ${\displaystyle \rightleftharpoons }$ CoA + N-acetyl-D-glucosamine

Thus, the two substrates of this enzyme are acetyl-CoA and D-glucosamine, whereas its two products are CoA and N-acetyl-D-glucosamine.

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:D-glucosamine N-acetyltransferase. Other names in common use include glucosamine acetylase, and glucosamine acetyltransferase. This enzyme participates in aminosugars metabolism.
