EC 3.2.1.70 Glucan 1,6-alpha-glucosidase. [3 PDB entries]    
2zic

Reaction: Hydrolysis of (1->6)-alpha-D-glucosidic linkages in (1->6)-alpha-D- glucans and derived oligosaccharides.
Other name(s): Exo-1,6-alpha-glucosidase. Glucodextranase.
Comments: 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.
