Note

  • do not confuse with amylase isoenzymes (index under AMYLASES (IM) + ISOENZYMES (IM) )

Scope note

  • An enzyme that hydrolyzes 1,6-alpha-glucosidic branch linkages in glycogen, amylopectin, and their beta-limit dextrins. It is distinguished from pullulanase (EC 3.2.1.41) by its inability to attack pullulan and by the feeble action of alpha-limit dextrins. It is distinguished from amylopectin 6-glucanohydrolase (EC 3.2.1.69) by its action on glycogen. With EC 3.2.1.69, it produces the activity called "debranching enzyme". EC 3.2.1.68.

History note

  • 91(75); was see under GLYCOSIDE HYDROLASES 1975-90
