In enzymology, an oligosaccharide 4-alpha-D-glucosyltransferase (EC 2.4.1.161) is an enzyme that catalyzes the chemical reaction in which the non-reducing terminal alpha-D-glucose residue is transferred from a 1,4-alpha-D-glucan to the 4-position of an alpha-D-glucan. This enzyme is useful in hydrolyzing oligosaccharides.
