In enzymology a N-acetyllactosaminide 3-alpha-galactosyltransferase (EC 2.4.1.87) is an enzyme that catalyzes the chemical reactionUDP-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-RThus 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.This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
