IntEnz Enzyme Nomenclature
EC 3.2.1.94

Names

Accepted name:
glucan 1,6-α-isomaltosidase
Other names:
G2-dextranase
exo-isomaltohydrolase
isomalto-dextranase
isomaltodextranase
1,6-α-D-glucan isomaltohydrolase
Systematic name:
6-α-D-glucan isomaltohydrolase

Reaction

Comments:

Optimum activity is on those 1,6-α-D-glucans containing 6, 7 and 8 glucose units; those containing 3, 4 and 5 glucose units are hydrolysed at slower rates.
