IntEnz Enzyme Nomenclature


Accepted name:
heparan-α-glucosaminide N-acetyltransferase
Other name:
acetyl-CoA:α-glucosaminide N-acetyltransferase
Systematic name:
acetyl-CoA:heparan-α-D-glucosaminide N-acetyltransferase



Brings about the acetylation of glucosamine groups of heparan sulfate and heparin from which the sulfate has been removed. Also acts on heparin. Not identical with EC glucosamine N-acetyltransferase or EC glucosamine-phosphate N-acetyltransferase.
