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. 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. 2018-08-31 In the study, we investigated the contribution of Ca 2+ to the thermostability of α-cyclodextrin glycosyltransferase (α-CGTase) from Paenibacillus macerans, which has two calcium-binding sites (CaI and CaII), and β-CGTase from Bacillus circulans, which contains an additional calcium-binding site (CaIII), consisting of Ala315 and Asp577.

CGTase from different microorganisms has different numbers of residues in 5 domains (A-E). CGTase from Bacillus circulans strains 8 has 80–108 residues in domain A, 185–192 residues in domain B, 407–494 residues in domain C, 495–580 residues in domain D and 581–684 residues in domain E . Cyclodextrin glucanotransferase [CGTase, E.C.2.4.1.19] is an extracellular enzyme, which catalyzes the formation of α−, β−, γ− CDs from starch. PubMed Abstract: The crystal structure of the cyclodextrin glycosyltransferase ( CGTase) from the thermophilic microorganism Thermoanaerobacterium Immobilized metal affinity chromatography (IMAC) was chosen as a method of purification for the recovery of CGTase from E. coli homogenate.

The enzyme is extremely heat stable and has a temperature optimum of 90-95°C at pH 6.0. It is active over a broad pH range, and exhibits more than 80% activity from pH 5.0-6.7. CGTase are known to catalyze four different transferase reactions: cyclization, coupling, disproportionation, and hydrolysis.
