Enzyme Information

2.4.1.19
Cyclomaltodextrin glucanotransferase.
based on mapping to UniProt P43379
Cyclizes part of a (1->4)-alpha-D-glucan chain by formation of a (1->4)- alpha-D-glucosidic bond.
-!- Cyclomaltodextrins (Schardinger dextrins) of various sizes (6, 7, 8, etc. glucose units) are formed reversibly from starch and similar substrates. -!- Also disproportionates linear maltodextrins without cyclizing (cf. EC 2.4.1.25).
