ENTRY       EC 3.2.1.94
NAME        Glucan 1,6-alpha-isomaltosidase
            Exo-isomaltohydrolase
            Isomalto-dextranase
CLASS       Hydrolases
            Glycosidases
            Hydrolysing O-glycosyl compounds
SYSNAME     1,6-alpha-D-Glucan isomaltohydrolase
REACTION    Hydrolysis of 1,6-alpha-D-glucosidic linkages in polysaccharides
            so as to remove successive isomaltose units from the non-reducing
            ends of the chains
SUBSTRATE   Polysaccharide
            H2O
PRODUCT     Isomaltose
COMMENT     Optimum activity is on those 1,6-alpha-D-glucans coantaining 6, 7
            and 8 glucose units; those containing 3, 4 and 5 glucose units
            are hydolysed at slower rate.
