Engineering of factors determining α‐amylase and cyclodextrin glycosyltransferase specificity in the cyclodextrin glycosyltransferase from Thermoanaerobacterium thermosulfurigenes EM1 [PDF]

open access: yesEuropean Journal of Biochemistry, 1998
The starch‐degrading enzymes α‐amylase and cyclodextrin glycosyltransferase (CGTase) are functionally and structurally closely related, with CGTases containing two additional domains (called D and E) compared to the three domains of α‐amylases (A, B and C). Amino acid residue 196 (Thermoanaerobacteriumthermosulfurigenes EM1 CGTase numbering) occupies a

Safety evaluation of the food enzyme cyclomaltodextrin glucanotransferase from the non‐genetically modified Anoxybacillus caldiproteolyticus strain TCM3‐539

open access: yesEFSA Journal, 2023
The food enzyme cyclomaltodextrin glucanotransferase ((1‐4)‐α‐d‐glucan:(1‐4)‐α‐d‐glucan 4‐α‐d‐[(1‐4)‐α‐d‐glucano]‐transferase; EC 2.4.1.19) is produced with the non‐genetically modified bacteria Anoxybacillus caldiproteolyticus strain TCM3‐539 by ...

Physico-chemical properties of corn starch modified with cyclodextrin glycosyltransferase [PDF]

open access: yes, 2016
Cyclodextrin glycosyltransferase (CGTase) has been used to produce cyclodextrins (CDs) from starches, but their ability to modify starches has been barely explored.

Studies on alkalophilic CGTase-producing bacteria and effect of starch on cyclodextrin-glycosyltransferase activity

open access: yesBrazilian Archives of Biology and Technology, 2004
The production of beta- and gamma -CD by CGTase from Bacillus firmus was studied, in regard to the effect of the source and concentration of starch on the yield of CD and CGTase activity.

Comparison of porous starches obtained from different enzyme types and levels [PDF]

open access: yes, 2016
The objective was to compare the action of different hydrolases for producing porous corn starches. Amyloglucosidase (AMG), α-amylase (AM), cyclodextrin-glycosyltransferase (CGTase) and branching enzyme (BE) were tested using a range of concentrations ...

Thermoanaerobacterium thermosulfurigenes cyclodextrin glycosyltransferase

open access: yesEuropean Journal of Biochemistry, 2002
Cyclodextrin glycosyltransferase (CGTase) uses an α‐retaining double displacement mechanism to catalyze three distinct transglycosylation reactions. To investigate these reactions as catalyzed by the CGTase from Thermoanaerobacterium thermosulfurigenes the enzyme was overproduced (8 mg·L−1 culture) using Bacillus subtilis as a host.

Cyclodextrin enhanced the soluble expression of Bacillus clarkii γ-CGTase in Escherichia coli

open access: yesBMC Biotechnology, 2018
Background Cyclodextrin glycosyltransferases (CGTases) catalyze the synthesis of cyclodextrins, which are circular α-(1,4)-linked glucans used in many applications in the industries related to food, pharmaceuticals, cosmetics, chemicals, and agriculture,

A Cyclodextrin-Based Controlled Release System in the Simulation of In Vitro Small Intestine

open access: yesMolecules, 2020
A novel cyclodextrin (CD)-based controlled release system was developed in the small intestine to control the rate of drug release, on the premise of enteric-coated tablets.

Molecular cloning of a cyclodextrin glucanotransferase gene from alkalophilic Bacillus sp. TS1-1 and characterization of the recombinant enzyme [PDF]

open access: yes, 2006
A cyclodextrin glucanotransferase (CGTase) gene from Bacillus sp. TS1-1 was isolated and cloned into Escherichia coli. Starting from TTG codon, there was an open reading frame composed of 2163 bp (721 amino acids).

Substrate binding to a cyclodextrin glycosyltransferase and mutations increasing the γ‐cyclodextrin production [PDF]

open access: yesEuropean Journal of Biochemistry, 1998
Bacterial cyclodextrin glycosyltransferases use starch to produce cyclic maltooligosaccharides (cyclodextrins) which are of interest in various applications. The cyclization reaction gives rise to a spectrum of ring sizes consisting of predominantly six to eight glucosyl units. Using the enzyme from Bacillus circulans strain no. 8, binding studies have
