ID 3.2.1.68 DE isoamylase. AN debranching enzyme. CA Hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen, CA amylopectin and their beta-limit dextrins. CC -!- Also readily hydrolyzes amylopectin. CC -!- Differs from EC 3.2.1.41 and EC 3.2.1.142 by its inability to CC hydrolyze pullulan, and by limited action on alpha-limit dextrins. CC -!- Maltose is the smallest sugar it can release from an alpha-(1->6)- CC linkage.
