ENZYME entry: EC

Accepted Name
Alternative Name(s)
Oligosaccharide alpha-1,6-glucosidase.
Reaction catalysed
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in some oligosaccharides produced from starch and glycogen by alpha-amylase, and in isomaltose
  • This enzyme, like EC, can release an alpha-1->6-linked glucose, whereas the shortest chain that can be released by EC, EC and EC 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
  • Differs from EC 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.
