CGTase can hydrolyze glucan chains, e.g. starch, in a manner similar to alpha-amylases, but differs in its ability to form cyclodextrins as reaction products. Cyclodextrins are formed from starch molecules through intramolecular transglycosylation, i.e. cyclization, and can be made up of 6 to 8 glucan residues, alpha-, beta-, and gamma-cyclodextrin, respectively. The enzyme is multifunctional |

CGTase catalyzes the transfer of dextrin units from cyclodextrins or longer dextrins to polyols, such as glycerol, sugars, and flavonoids |
| 2.4.1.19 | more |
CGTase is an extracellular enzyme capable of converting starch or starch derivatives into cyclodextrins through an intramolecular transglycosylation reaction. Cyclodextrins are cyclic, nonreducing oligoglucopyranose molecules linked via alpha(1,4)-glycosidic bonds |

CGTases produce a mixture of cyclodextrins from starch consisting of 6 alpha, 7 beta, or 8 gamma glucose units, specificity, overview |
