beta-D-GlcNAc-(1->2)-[beta-D-GlcNAc-(1->4)]-alpha-D-Man-(1->3)-[beta-D-GlcNAc-(1->2)-[beta-D-GlcNAc-(1->4)]-[beta-D-GlcNAc-(1->6)]-alpha-D-Man-(1->6)]-beta-D-Man-(1->4)-beta-D-GlcNAc-(1->4)-beta-D-GlcNAc-N-Asn-[protein]
Comment
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.
