In enzymology, a 1,4-alpha-glucan 6-alpha-glucosyltransferase (EC 184.108.40.206) is an enzyme that catalyzes the chemical reaction that transfers an alpha-D-glucosyl residue in a 1,4-alpha-D-glucan to the primary hydroxyl group of glucose or 1,4-alpha-D-glucan.
This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 1,4-alpha-D-glucan:1,4-alpha-D-glucan(D-glucose) 6-alpha-D-glucosyltransferase. Other names in common use include oligoglucan-branching glycosyltransferase, 1,4-alpha-D-glucan 6-alpha-D-glucosyltransferase, T-enzyme, and D-glucosyltransferase.
