In enzymology, a lipopolysaccharide N-acetylglucosaminyltransferase (EC 2.4.1.56) is an enzyme that catalyzes the chemical reaction

UDP-N-acetyl-D-glucosamine + lipopolysaccharide [math]\displaystyle{ \rightleftharpoons }[/math] UDP + N-acetyl-D-glucosaminyllipopolysaccharide

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

This enzyme participates in lipopolysaccharide biosynthesis and glycan structures - biosynthesis 2.

Nomenclature

This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-N-acetyl-D-glucosamine:lipopolysaccharide N-acetyl-D-glucosaminyltransferase. Other names in common use include UDP-N-acetylglucosamine-lipopolysaccharide, N-acetylglucosaminyltransferase, uridine diphosphoacetylglucosamine-lipopolysaccharide, and acetylglucosaminyltransferase.
