Hexosyltransferases
Sysname
(1->4)-alpha-D-glucan:(1->4)-alpha-D-glucan 4-alpha-D-[(1->4)-alpha-D-glucano]-transferase (cyclizing)
Reaction(IUBMB)
Cyclizes part of a (1->4)-alpha-D-glucan chain by formation of a (1->4)-alpha-D-glucosidic bond
Reaction(KEGG)
(other) R11260
Comment
Cyclomaltodextrins (Schardinger dextrins) of various sizes (6,7,8, etc. glucose units) are formed reversibly from starch and similar substrates. Will also disproportionate linear maltodextrins without cyclizing (cf. EC 2.4.1.25, 4-alpha-glucanotransferase).
