EC 18.104.22.168 - Isoamylase
IntEnz Enzyme Nomenclature
- Hydrolysis of (1right6)-alpha-D-glucosidic branch linkages in glycogen, amylopectin and their beta-limit dextrins
Also readily hydrolyses amylopectin. Differs from EC 22.214.171.124 (pullulanase) and EC 126.96.36.199 (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.
