Enzyme Information

3.2.1.68
Isoamylase.
based on mapping to UniProt P10342
Hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen, amylopectin and their beta-limit dextrins.
-!- Also readily hydrolyzes amylopectin. -!- Differs from EC 3.2.1.41 and EC 3.2.1.142 by its inability to hydrolyze pullulan, and by limited action on alpha-limit dextrins. -!- Maltose is the smallest sugar it can release from an alpha-(1->6)- linkage.
