| Name |
glucan 1,6-alpha-isomaltosidase;
exo-isomaltohydrolase;
isomalto-dextranase;
isomaltodextranase;
G2-dextranase;
1,6-alpha-D-glucan isomaltohydrolase
|
|---|
| Class |
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
 |

| Sysname |
6-alpha-D-glucan isomaltohydrolase
|
|---|
| Reaction(IUBMB) |
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in polysaccharides, to remove successive isomaltose units from the non-reducing ends of the chains
|
|---|
| Comment |
Optimum activity is on those 1,6-alpha-D-glucans containing 6, 7 and 8 glucose units; those containing 3, 4 and 5 glucose units are hydrolysed at slower rates.
