: Transfers a segment of a 1,4-α-D-glucan chain to a primary hydroxyl group in a similar glucan chain, forming a 1,6 branch point. Converts amylose into amylopectin. The Common name requires a qualification depending on the product, glycogen or amylopectin, e.g. glycogen branching enzyme, amylopectin branching enzyme. The latter has frequently been termed Q-enzyme.; Hydrolysis of (1->6)-α-D-glucosidic branch linkages in glycogen, amylopectin and their β-limit dextrins. Also readily hydrolyses amylopectin. Differs from EC 3.2.1.41 (pullulanase) and EC 3.2.1.142 (limit dextrinase) by its inability to hydrolyse pullulan, and by limited action on α-limit dextrins. Maltose is the smallest sugar it can release from an α-(1->6)-linkage.
