| Accepted name: |
glucan 1,6-α-isomaltosidase |
| Reaction: |
Hydrolysis of (1→6)-α-D-glucosidic linkages in polysaccharides, to remove successive isomaltose units from the non-reducing ends of the chains |
| Other name(s): |
exo-isomaltohydrolase; isomalto-dextranase; isomaltodextranase; G2-dextranase; 1,6-α-D-glucan isomaltohydrolase |
| Systematic name: |
6-α-D-glucan isomaltohydrolase |
| 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. |
