In enzymology, a glucosamine N-acetyltransferase () is an enzyme that catalyzes the chemical reaction acetyl-CoA + D-glucosamine 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. References EC 2.3.1 Enzymes of unknown structure
