Cyclodextrin glycosyltransferase (CGTase) is an enzyme of the alpha-amylase family, which uses a double displacement mechanism to process alpha-linked glucose polymers. We have determined two X-ray structures of CGTase complexes, one with an intact substrate at 2.1 A resolution, and the other with a covalently bound reaction intermediate at 1.8 A resolution.

However, the low specificity and activity of soluble γ-CGTase increase the production cost of γ-CD, thereby limiting its applications. 2017-05-19 cgtase. Organism.

Cyclodextrin glucanotransferases (CGTase; E.C 2.4.1.19) belonging to the glycoside hydrolase family 13 (GH 13) are widely used as catalysts in starch conversion processes (Han et al. 2014). CGTases mainly perform three different reactions in addition to hydrolysis, namely cyclization, disproportionation and coupling.

CGTase are known to catalyze four different transferase reactions: cyclization, coupling, disproportionation, and hydrolysis. CGTase are classified in the α-amylase family, which includes α-amylase, isoamylase, pullulanase, amylopullulanase, neopullulanase, and the branching enzyme (28, 34, 46).
