Glucan 1,6-α-isomaltosidase (EC 3.2.1.94, exo-isomaltohydrolase, isomalto-dextranase, isomaltodextranase, G2-dextranase, 1,6-α-D-glucan isomaltohydrolase) is an enzyme with systematic name 6-α-D-glucan isomaltohydrolase.[1][2] 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
