An especially interesting and unique family 13 enzyme is cyclodextrin glycosyltransferase (CGTase). 1 CGTase forms circular α(1→4)-linked oligoglucosides called cyclodextrins from linear α(1→4)-linked glucans via an intramolecular transglycosylation reaction known as cyclization (see Fig. 1).

Bacillus macerans cyclodextrin glycosyltransferase (CGTase) (EC 2.4.1.19) was covalently immobilised on Eupergit C and used in a packed-bed reactor to investigate the continuous production of long-carbohydrate-chain alkyl glycosides from alpha-cyclodextrin (alpha-CD) and n-dodecyl-(1,4)-beta-maltopyranoside (C(12)G(2)beta). The effects of buffer ion strength and pH, and enzyme loading on …

An especially interesting and unique family 13 enzyme is cyclodextrin glycosyltransferase (CGTase). 1 CGTase forms circular α(1→4)-linked oligoglucosides called cyclodextrins from linear α(1→4)-linked glucans via an intramolecular transglycosylation reaction known as cyclization (see Fig. 1). 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. The cyclomaltodextrin glucanotransferase (CGTase, EC 2.4.1.19) is an enzyme capable of converting starch into CD molecules.

G1 was successfully isolated and cloned into Escherichia coli. Analysis of the nucleotide sequence revealed the presence of an open reading frame of 2,109 bp and encoded a 674 amino acid protein. Purified CGTase exhibited a molecular weight of 75 kDa and had optimum activity at pH 6 and 60°C cgtase cyclodextrin amino acid bacillus amino Prior art date 1990-03-27 Legal status (The legal status is an assumption and is not a legal conclusion.

Cyclodextrin glucanotransferase (CGTase) is an important industrial enzyme which is used to produce cyclodextrins. CGTase genes from more than 30 bacteria have been isolated and several of the enzymes have been identified and biochemically characterized. For a better understanding of the reaction mechanism and function of CGTase, the enzyme has been analyzed at gene level and protein level

The enzyme was purified and displayed optimum activity at 50°C and pH 6 … One family member, cyclodextrin glycosyltransferase (CGTase), has an uncommonly high transglycosylation activity and is able to form cyclodextrins. We have determined the 2.0 and 2.5 Å X-ray structures of E257A/D229A CGTase in complex with maltoheptaose and maltohexaose.

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).
