N-Acetyllactosaminide beta-1,6-N-acetylglucosaminyl-transferase (EC 2.4.1.150) is an enzyme that catalyzes the chemical reaction converting UDP-N-acetyl-D-glucosamine and beta-D-galactosyl-1,4-N-acetyl-D-glucosaminide to UDP and N-acetyl-beta-D-glucosaminyl-1,6-beta-D-galactosyl-1,4-N-acetyl-D-glucosaminide. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. N-Acetyllactosaminide beta-1,6-N-acetylglucosaminyl-transferase is a branching enzyme that turn linear poly N-acetyllactosaminoglycans into branched ones. The enzyme was initially identified in microsomal preparations from hog gastric mucosa. A cDNA of the human enzyme was first isolated in 1993 and expressed in Chinese hamster ovary (CHO) cells.

The enzyme from mammals introduces the blood group I antigen during embryonic development. The I antigen is found on membrane proteins of the red blood cells and some other cell types, as well as different body secretions of developing fetuses and newborn infants, while the I antigen is found in all adults. The i antigen undergoes gradual conversion to the I antigen in newborn infants. Both antigens are based entirely on Type 2 (N-acetyllactosamine) chains. The basic i structure is an unbranched polylactosamine. Importantly, the key step in the conversion of the i antigen to the I antigen is catalyzed by N-acetyllactosaminide β-1,6-N-acetylglucosaminyl-transferase, which introduces the branching by adding a GlcNAc residue to the galactose. This process is closely associated with the development and maturation of erythroid cells.
