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