ID   2.4.1.396
DE   4,6-alpha-glucanotransferase (linear and branched substrates, branched
DE   products).
CA   formation of a branched isomalto/malto-polysaccharide from branched
CA   malto-oligosaccharides.
CC   -!- The enzyme, discovered in several bacterial species, is similar to
CC       EC 2.4.1.395 yet is not able 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 endo alpha(1->4) linkages from the non-reducing end of
CC       maltooligosaccharides and adding the resulting oligosaccharides to
CC       the non-reducing end of alpha-D-glucan chains that terminate with a
CC       residue linked by an alpha-(1->4) linkage, forming an alpha(1->6)
CC       linkage.
CC   -!- The enzyme is not able to form successive alpha(1->6) linkages.
CC   -!- Unlike EC 2.4.1.394, which can only act on linear substrates, this
CC       enzyme is able to act on both linear and branched substrates, and can
CC       form the branched reuteran type of alpha-glucan.
