The systematic name of this enzyme class is UDP-N-acetyl-D-glucosamine:beta-D-galactosyl-1,4-N-acetyl-D-glucosam ine beta-1,3-acetyl-D-glucosaminyltransferase. Other names in common use include uridine diphosphoacetylglucosamine-acetyllactosaminide, beta1->3-acetylglucosaminyltransferase, poly-N-acetyllactosamine extension enzyme, Galbeta1->4GlcNAc-R beta1->3 N-acetylglucosaminyltransferase, UDP-GlcNAc:GalR, beta-D-3-N-acetylglucosaminyltransferase, N-acetyllactosamine beta(1-3)N-acetylglucosaminyltransferase, UDP-GlcNAc:Galbeta1->4GlcNAcbeta-Rbeta1->3-N-, acetylglucosaminyltransferase, and GnTE.  This enzyme participates in 4 metabolic pathways: keratan sulfate biosynthesis, glycosphingolipid biosynthesis – neo-lactoseries, glycan structures – biosynthesis 1, and glycan structures – biosynthesis 2.References[edit]Takeya A, Hosomi O, Kogure T (1985). “The presence of N-acetyllactosamine and lactose: beta (1-3)N-acetylglucosaminyltransferase activity in human urine”.
