Protein Type Enzyme
Biological Properties
General Function Involved in beta-1,4-mannosylglycoprotein 4-beta-N-acet
Specific Function It is involved in the regulation of the biosynthesis and biological function of glycoprotein oligosaccharides. Catalyzes the addition of N-acetylglucosamine in beta 1-4 linkage to the beta-linked mannose of the trimannosyl core of N-linked sugar chains. It is one of the most important enzymes involved in the regulation of the biosynthesis of glycoprotein oligosaccharides.
