In enzymology a lipopolysaccharide 3-alpha-galactosyltransferase (EC 2.4.1.44) is an enzyme that catalyzes the chemical reactionUDP-galactose + lipopolysaccharide UDP + 3-alpha-D-galactosyl-[lipopolysaccharide glucose]Thus the two substrates of this enzyme are UDP-galactose and lipopolysaccharide whereas its two products are UDP and [[3-alpha-D-galactosyl-[lipopolysaccharide glucose]]].This enzyme belongs to the family of glycosyltransferases specifically the hexosyltransferases.
