Enzyme Information

3.2.1.70
Glucan 1,6-alpha-glucosidase.
based on mapping to UniProt Q99040
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in (1->6)-alpha-D- glucans and derived oligosaccharides.
-!- Hydrolysis is accompanied by inversion at C-1, so that new reducing ends are released in the beta-configuration. -!- Dextrans and isomaltosaccharides are hydrolyzed, as is isomaltose, but very slowly. -!- The enzyme from some sources also possesses the activity of EC 3.2.1.59.
