2.4.1.19	alpha-1,4-glucan + glycosyl acceptor	-	
2.4.1.19	additional information	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	
2.4.1.19	additional information	isolation of alkaliphilic Bacillus strains and determination of their phylogenetic and phenotypic characteristics, overview	
2.4.1.19	additional information	CGTase catalyzes the transfer of dextrin units from cyclodextrins or longer dextrins to polyols, such as glycerol, sugars, and flavonoids	
2.4.1.19	additional information	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	
2.4.1.19	additional information	CGTases produce a mixture of cyclodextrins from starch consisting of 6 alpha, 7 beta, or 8 gamma glucose units, specificity, overview	
2.4.1.19	additional information	cyclodextrin glucanotransferases produce a mixture of cyclic alpha-(1,4)-linked oligosaccharides, cyclodextrins, from starch. The enzyme from Anaerobranca gottschalkii produces alpha-cyclodextrins	
2.4.1.19	additional information	cyclodextrin glucanotransferases produce a mixture of cyclic alpha-(1,4)-linked oligosaccharides, cyclodextrins, from starch. The enzyme from Bacillus agaradhaerens produces beta-cyclodextrins	
2.4.1.19	additional information	cyclodextrin glucanotransferases produce a mixture of cyclic alpha-(1,4)-linked oligosaccharides, cyclodextrins, from starch. The enzyme from Bacillus clarkii produce beta-cyclodextrins, except for strain 290-3 that also produces gamma-cyclodextrins	
2.4.1.19	additional information	cyclodextrin glucanotransferases produce a mixture of cyclic alpha-(1,4)-linked oligosaccharides, cyclodextrins, from starch. The enzyme from Bacillus clarkii produces 80% gamma-cyclodextrins with an overall conversion of starch into cyclodextrins of 14%
