ENZYME entry: EC 3.2.1.10

Accepted Name
Oligo-1,6-glucosidase.
Alternative Name(s)
Alpha-methylglucosidase.
Isomaltase.
Oligosaccharide alpha-1,6-glucosidase.
Sucrase-isomaltase.
Reaction catalysed
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in some oligosaccharides produced from starch and glycogen by alpha-amylase, and in isomaltose
Comment(s)
  • This enzyme, like EC 3.2.1.33, can release an alpha-1->6-linked glucose, whereas the shortest chain that can be released by EC 3.2.1.41, EC 3.2.1.142 and EC 3.2.1.68 is maltose.
  • It also hydrolyzes 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 catalyzes the reaction of EC 3.2.1.48.
  • Differs from EC 3.2.1.33 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.
