|Cyclizes part of a (1->6)-alpha-D-glucan chain by formation of a (1->6)-alpha-D-glucosidic bond|
- Specific for (1->6)-alpha-D-glucans (dextrans) and, unlike
cyclomaltodextrin glucanotransferase (EC 220.127.116.11), without activity
toward (1->4)-alpha-D-glucans, such as amylose.
- It also has no activity on oligosaccharides, such as amylopectin and
pullulan, containing (1->6)-alpha-D-glucosidic linkages at branch
- The enzyme from Bacillus circulans T-3040 has been shown to form
cycloisomalto-oligosaccharides of three sizes (7, 8 and 9 glucose
- It will also catalyze the disproportionation of two isomalto-
oligosaccharides molecules to yield a series of isomalto-
oligosachharides and the addition of D-glucose to cycloisomalto-
oligosaccharides with ring opening to form isomalto-oligosaccharides.
