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.

γ-Cyclodextrin glycosyltransferase (γ-CGTase) catalyzes the biotransformation of low-cost starch into valuable γ-cyclodextrin (γ-CD), which is widely applied in biotechnology, food, and pharmaceutical industries. 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. Anaerobranca gottschalkii. Status.

The extracellular enzyme cyclodextrin glucanotransferase (CGTase) synthesizes cyclic malto-oligosaccharides called cyclodextrins (CDs) from starch and related α-1,4-glucans. CGTases are produced by a variety of bacteria, mainly Bacillus species, by submerged culture in complex medium. CGTases differ in the amount and types of CDs produced.

Most of the CGTase producing bacteria are naturally from the Bacillus genus and most of these Bacillus species produce the CGTase enzyme extracellularly, due to the functioning of signal peptide.In the cyclization reaction, starch is cleaved and the intramolecular ends are joined to form closed circular structures. Publisher Summary This chapter discusses the purification and action of cyclodextrin-producing enzyme (CGTase). Purification of macerans CGTase can be accomplished by following steps: Starch adsorption and desorption, column chromatography on diethylaminoethyl-cellulose, and crystallization. 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.

CGTase enzymes immobilized on various supports such as porous glass beads or glyoxyl-agarose have been previously used to achieve this objective. Nevertheless, the attachment of biocatalysts on conventional supports is associated with numerous drawbacks, including enzyme leaching prominent in physical adsorption, reduced activity as a result of chemisorption, and increased mass transfer 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.

CGTases differ in the amount and types of CDs produced. In addition, CGTase production is highly dependent on the strain, medium composition and culture conditions. Objectives: Cyclodextrin glucanotransferase (CGTase) is a multifunctional industrial enzyme, which undergoes cyclization reaction to converts starch into Cyclodextrin (CD).

CGTase, was selected from B. cereus YUPP-10 by a constructed fos-mid library. We discovered that CGTase has antimicrobial activity and induces resistance. In addition, we have revealed the key do-mains responsible for its hydrolytic activity and resistance induction. Further experiments demonstrated that CGTase is a potential func - CGTase is an important industrial enzyme that can transfer starch to glycosyl groups to form cyclodextrin (Li et al., 2014c; Qi et al., 2007). CGTase has been found in many bacteria, including Bacillus spp. (Chen et al., 2018; Gimenez et al., 2019; Yap et al., 2010) and Paenibacillus spp.
