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)
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).
History
EC 2.4.1.19 created 1961
Pathway
ec00500 Starch and sucrose metabolism
Orthology
K00701 cyclomaltodextrin glucanotransferase
