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 …

The cyclodextrin glucanotransferase (CGTase, EC 2.4.1.19) gene from Bacillus sp. 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

Therefore, the present study aimed Cyclodextrin glucanotransferase (CGTase) is a unique type of α - amylase which produces cyclodextrins (CDs) from starch, besides degrading starch to maltooligosaccharides. 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.

The optimum pH of 6.0 and 60 °C temperature were found to be the best for CGTase activity. Purified CGTase showed 5.18 kcal/mol activation energy (Ea). Objectives: Cyclodextrin glucanotransferase (CGTase) is a multifunctional industrial enzyme, which undergoes cyclization reaction to converts starch into Cyclodextrin (CD). Due to their potential properties, CDs had been discovered to more. The cyclodextrin glucanotransferase (CGTase, EC 2.4.1.19) gene from Bacillus sp. 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 The CGTase enzyme obtained from the M5 clone had Km and Vmax values 13.59 mg/mL and 1153 µmol/(mg min), respectively.
