In enzymology, a N-acetyllactosaminide 3-alpha-galactosyltransferase (EC 184.108.40.206) is an enzyme that catalyzes the chemical reaction: UDP-galactose + beta-D-galactosyl-(1->4)-beta-N-acetyl-D-glucosaminyl-R → UDP + alpha-D-galactosyl-(1->3)-beta-D-galactosyl-(1->4)-beta-N- acetylglucosaminyl-R. Thus, the two substrates of this enzyme are UDP-galactose and [[beta-D-galactosyl-(1->4)-beta-N-acetyl-D-glucosaminyl-R]], whereas its 3 products are UDP, [[alpha-D-galactosyl-(1->3)-beta-D-galactosyl-(1->4)-beta-N-]], and acetylglucosaminyl-R.
