- In enzymology, a cyclomaltodextrin glucanotransferase (also cyclodextrin glycosyl transferase or CGTase for short) (EC 2.4.1.19) is an enzyme that catalyzes the chemical reaction of cyclizing part of a 1,4-alpha-D-glucan molecule through the formation of a 1,4-alpha-D-glucosidic bond. They are bacterial enzymes belonging to the same family of the α-amylase specifically known as glycosyl-hydrolase family 13. This peculiar enzyme is capable of catalyzing more than one reaction with the most important being the synthesis of non-reducing cyclic dextrins known as cyclodextrins starting from starch, amylose, and other polysaccharides. CGTase is an enzyme common to many bacterial species, in particular of the Bacillus genus (e.g. B. circulans, B. macerans and B. stearothermophilus) and Brevibacillus brevis. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is 1,4-alpha-D-glucan 4-alpha-D-(1,4-alpha-D-glucano)-transferase (cyclizing). Other names in common use include Bacillus macerans amylase, cyclodextrin glucanotransferase, alpha-cyclodextrin glucanotransferase, alpha-cyclodextrin glycosyltransferase, beta-cyclodextrin glucanotransferase, beta-cyclodextrin glycosyltransferase, gamma-cyclodextrin glycosyltransferase, cyclodextrin glycosyltransferase, cyclomaltodextrin glucotransferase, cyclomaltodextrin glycosyltransferase, konchizaimu, alpha-1,4-glucan 4-glycosyltransferase, cyclizing, BMA, CGTase, and neutral-cyclodextrin glycosyltransferase.

Inoltre renderebbe non proporzionate le maltodestrine lineari senza la ciclizzazione. (cf.la 4-alfa-glucanotransferasi, numero EC 2.4.1.25). (it)
