N-acetyllactosamine synthase (EC 2.4.1.90, formerly EC 2.4.1.98) catalyzes the transfer of galactose from UDP-gal to suitable acceptor. In vivo it forms a terminal GlcNAc residue on an N-linked oligosaccharide of a glycoprotein. In vitro it may transfer a galactose to free GlcNAc, forming N-acetyllactosamine or to the terminal GlcNAc of a glycoprotein. The catalytic reaction needs divalent cations, such as Mn²⁺, Ca²⁺, and Mg²⁺.

This enzyme belongs to the glycosyltransferases, which are membrane-bound enzymes of the Golgi complex and must function in the lipid-rich environment of the bilayer. Recently, the control of the activity of this and other glycosyltransferases has been studied extensively at the substrate level. It is believed that lipids will exert a regulatory effect on these enzymes quite apart from those observed at the substrate level. N-acetyllactosamine synthase has significances in biotechnology, medicine, and biosynthesis. For example, this enzyme can be useful in the glycosylation of cytokines, enzymes, or other glycosylated biological macromolecules, modifying their functions for use in medical therapies. It can also contribute to the synthesis of N-acetyllactosamine, which is thought to play roles in normal cellular recognition as well as in malignant transformation and metastasis.
