ENZYME entry: EC 3.2.1.68

Accepted Name
Isoamylase.
Alternative Name(s)
Debranching enzyme.
Reaction catalysed
Hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen, amylopectin and their beta-limit dextrins
Comment(s)
  • 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.
