| Comment(s) |
|---|
- The enzyme, characterized from hen oviduct membranes, participates in
the processing of N-glycans in the Golgi apparatus.
- It transfers GlcNAc in beta-1-4 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.
