Glucan 1,6-α-isomaltosidase

Glucan 1,6-α-isomaltosidase (, exo-isomaltohydrolase, isomalto-dextranase, isomaltodextranase, G2-dextranase, 1,6-α- D -glucan isomaltohydrolase) is an enzyme with systematic name 6-α- D -glucan isomaltohydrolase. It catalyses hydrolysis of (1→6)-β- D -glucosidic linkages in polysaccharides, to remove successive isomaltose units from the non-reducing ends of the chains

Optimum activity is on those 1,6-α- D -glucans containing 6, 7 and 8 glucose units.
