IUBMB Comments
The enzyme acts on poly-N-acetyllactosamine [glycan chains of beta-D-galactosyl-(1->4)-N-acetyl-D-glucosamine units connected by beta(1,3) linkages] attached to proteins or lipids. It transfers a GlcNAc residue by beta(1,6)-linkage to galactosyl residues close to non-reducing terminals, introducing a branching pattern known as I branching.
