EC Number 3.2.1.68
CAS Registry Number 9067-73-6
Comments 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 ¦Á-limit dextrins. Maltose is the smallest sugar it can release from an ¦Á-(1¡ú6)-linkage.
Cofactor
History
Reactions Hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen, amylopectin and their beta-limit dextrins.
