2.4.1.201 alpha-1,6-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferaseIUBMB Comments
Requires a high concentration of Mn2+ for maximal activity. The enzyme, characterized from hen oviduct membranes, participates in the processing of N-glycans in the Golgi apparatus. It transfers GlcNAc in beta1-4 linkage to a D-mannose residue that already has GlcNAc residues attached at positions 2 and 6 by beta linkages. No homologous enzyme appears to exist in mammals.

evaluation of a highly sensitive method for determination of the activity of GnT VI using a fl uorescently labeled tetraantennary oligosaccharide as an acceptor substrate. GnT VI stringently requires beta1,6-N-acetylglucosaminylation on the Manalpha1-6 arm (GnT V product, EC 2.4.1.155) as an acceptor substrate. Agalacto-triantennary oligosaccharide (GnT V product) can also be used as an alternate substrate

GlcNAc and tet-induced Mgat6 increases the levels of many metabolites in HeLa cells, and HEK293 cells, and tet-induced Mgat5 changes in the N-glycan distributions, N-glycans profiles of transgenic HeLa cells, overview. Tet-inducible Mgat5 enhances amino acid uptake and growth in nutrient-poor conditions. The Mgat5, EC 2.4.1.155, product is the preferred acceptor for Mgat6, which adds a GlcNAcbeta1,4 branch that is not present in mammals, Mgat6 enhances functionality of N-glycan branching in mammalian cells
