This enzyme, like EC?3.2.1.33?(amylo-¦Á-1,6-glucosidase), can release an ¦Á-1¡ú6-linked glucose, whereas the shortest chain that can be released by EC?3.2.1.41?(pullulanase), EC?3.2.1.142?(limit dextrinase), and EC?3.2.1.68?(isoamylase) is maltose. It also hydrolyses isomaltulose (palatinose), isomaltotriose and panose, but has no action on glycogen or phosphorylase limit dextrin. The enzyme from intestinal mucosa is a single polypeptide chain that also catalyses the reaction of EC?3.2.1.48?(sucrose ¦Á-glucosidase). Differs from EC?3.2.1.33?(amylo-¦Á-1,6-glucosidase) in its preference for short-chain substrates and in its not requiring the 6-glucosylated residue to be at a branch point, i.e. linked at both C-1 and C-4. |
