3.2.1.70 |
| Accepted name: |
glucan 1,6-α-glucosidase |
| Reaction: |
Hydrolysis of (1→6)-α-D-glucosidic linkages in (1→6)-α-D-glucans and derived oligosaccharides |
| Other name(s): |
exo-1,6-β-glucosidase; glucodextrinase; glucan α-1,6-D-glucohydrolase |
| Systematic name: |
glucan 6-α-D-glucohydrolase |
| Comments: |
Hydrolysis is accompanied by inversion at C-1, so that new reducing ends are released in the β-configuration. Dextrans and isomaltosaccharides are hydrolysed, as is isomaltose, but very slowly. The enzyme from some sources also possesses the activity of EC 3.2.1.59 (glucan endo-1,3-α-glucosidase). |
