Accepted name: high-mannose-oligosaccharide β-1,4-N-acetylglucosaminyltransferase

Reaction: Transfers an N-acetyl-D-glucosamine residue from UDP-N-acetyl-D-glucosamine to the 4-position of a mannose linked α-(1→6) to the core mannose of high-mannose oligosaccharides produced by Dictyostelium discoideum

Other name(s): uridine diphosphoacetylglucosamine-oligosaccharide acetylglucosaminyltransferase; acetylglucosamine-oligosaccharide acetylglucosaminyltransferase; UDP-GlcNAc:oligosaccharide β-N-acetylglucosaminyltransferase

Systematic name: UDP-N-acetyl-D-glucosamine:high-mannose-oligosaccharide β-1,4-N-acetylglucosaminyltransferase

Comments: The activity of the intersecting mannose residue as acceptor is dependent on two other mannose residues attached by α-1,3 and α-1,6 links.
