ENZYME entry: EC 2.4.1.394

PURL: https://purl.expasy.org/enzyme/EC/2.4.1.394
Accepted Name
4,6-alpha-glucanotransferase (linear substrates/linear products)
Reaction catalysed
formation of a linear isomalto/malto-polysaccharide from linear malto-oligosaccharides
Comment(s)
  • The enzyme, originally discovered in lactic acid bacteria but later found in other organisms, is similar to EC 2.4.1.395 yet is not able to act on sucrose.
  • The enzyme, which belongs to the glycoside hydrolase 70 (GH70) family, possesses both hydrolase and transglycosylase activities, cleaving alpha(1->4) linkages from the non-reducing end of linear maltooligosaccharides and synthesizing linear alpha(1->6)-glucan chains.
  • It also possesses an endo-alpha(1->4)-glycosidase activity.
  • Due to its narrow binding groove, it is not able to act on branched substrates. cf. EC 2.4.1.396.
