Enzyme Commission Primary Name: cyclomaltodextrin glucanotransferase

Enzyme Commission Synonyms: Bacillus macerans amylase, cyclodextrin glucanotransferase, α-cyclodextrin glucanotransferase, α-cyclodextrin glycosyltransferase, β-cyclodextrin glucanotransferase, β-cyclodextrin glycosyltransferase, γ-cyclodextrin glycosyltransferase, cyclodextrin glycosyltransferase, cyclomaltodextrin glucotransferase, cyclomaltodextrin glycosyltransferase, konchizaimu, α-1,4-glucan 4-glycosyltransferase, cyclizing, BMA, CGTase, neutral-cyclodextrin glycosyltransferase, 1,4-α-D-glucan 4-α-D-(1,4-α-D-glucano)-transferase (cyclizing)

Taxonomic Range: Bacteria

Enzyme Commission Summary:
The enzyme cyclizes a part of a (1→4)-α-D-glucan chain by formation of a (1→4)-α-D-glucosidic bond.

Cyclodextrins (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, 4-α-glucanotransferase).
