In enzymology, a cyclomaltodextrin glucanotransferase (also cyclodextrin glycosyl transferase or CGTase for short) (EC 2.4.1.19) is an enzyme that catalyzes the chemical reaction of cyclizing part of a 1,4-alpha-D-glucan molecule through the formation of a 1,4-alpha-D-glucosidic bond.

The fragment ions were appeared owing to the analysis condition of HPLC/QDa, accordingly, DA3 (m/z+ 741) showed its fragment (m/z+ 417) by reduction of molecular weight of two glucosyl (MW 162 × 2) moieties. Cyclodextrin glycosyltransferases (CGTases) (EC 2.4.1.19) catalyze the conversion of starch or starch derivates into mixtures of α-, β-, and γ-cyclodextrins. Because time-consuming and expensive purification procedures hinder the widespread application of single-ingredient cyclodextrins, enzymes with enhanced specificity are needed. In this study, we tested the hypothesis that the α Amano Enzyme, Inc. (Japan), and was used without further puriﬁ-cation. Soluble starch, which was used as the substrate for the CGTase activityassay,waspurchasedfromMerck(Germany).

Kei Nakagawa, Hiroki Amano, Magnus Persson & Ronny Berndtsson, 2021 Dec, and cyclodextrin glucanotransferase (CGTase)‐catalysed transglycosylation. CGTase was purchased from Amano Enzyme Europe Ltd (Milton Keynes, UK) and Toruzyme 3.0L was obtained from Novozyme A/S (Bagsvaerd, Denmark). Dodecyl-β-maltooctaoside was produced in-house as described previously (Svensson et al. 2009a).

In our work, the CGTase from Thermoanaerobacter sp. (Toruzyme 3.0 L) gave a higher yield than that from Bacillus macerans (CGTase Amano). In contrast with the CGTase from Bacillus macerans (the HPLC chromatogram showed four different compounds with increasing concentration, indicating the formation of the so‐called analogous series, Figure 2 glycosyltransferase (CGTase) gave rise to a signiﬁcant formation of glycosylated products.

1995-12-01 · In that case, CGTase was used in cyclodextrins producing reaction only, the amount of enzyme used by this article's method was 35-40% of Amano's. CGTase is used in liquefaction of starch and production of cyclodextrins, Cyclodextrin production with heat-treated starch: T. J. Kim et al. the amount of enzyme used by this article's method was 5. 17-20% of Amano's.

Cyclodextrin glucanotransferase from Bacillus macerans (CGTase Amano) was purchased from Amano Pharmaceutical Co., Ltd. (Nagoya, Japan). Its optimum reaction pH is 6.0 and its temperature is 60 C. The buffer was 50 mm sodium phosphate. Soluble starch was purchased from Yakuri Pure Chemicals Co., Ltd. (Osaka, Japan).

この物質をつくる酵素をサイクロデキストリングルカノトランスフェラーゼ（CGTase）といいます。そこに空間があるから。この輪の中には、何が入れられるでしょうか？ studies on glycosyltransferases other than CGTase, we are interested in the action of CGTase in producing cyclic glucans larger than CDs. In this paper, we investigated the initial action of CGTase from an alkalophilic Bacillus sp. A2-5a (25) on synthetic amylose and found that the CGTase also produced CGTase A reaction mixture (300 µL) containing 0.15 mg nerol, 30 mg maltose, 20 mM potassium phosphate buﬀer (pH 7.0), and 2 units of transglucosidase or 0.03 units of CGTase were incubated at 30°C for 24 h. The enzymatic activity was determined by thin-layer chromatography (TLC) or HPLC. One unit of trans- CIs by the action of CGTase. The reaction condition for synthesis of branched CI was as follows; 4.5 g of maltose, 1.0 g of CI-7, 10 ml of 100 mM acetate buffer (pH 5.5), 85 ml of deionized water, and 3 ml of CGTase solution (300 U/ml) were mixed and incubated at 40t for 24 h. コンテンツ説明文 회사명 : 바이오시스 / 대표 : 박동주 / 주소 : 부산광역시 해운대구 달맞이길62번길 3 (한신빌딩 4층) / tel : 051-746-7605 / fax : 051-746-7607 The present invention provides a method for producing isoquercitrin, α-glycosylisoquercitrin, and rhamnose, the method comprising a step of naringin-degrading enzyme treatment during the isoquercitrin production from rutin in the presence of an edible component, such as gelatin, wheat gluten, chitosan, lecithin, a glycerol fatty acid ester, xanthan gum, carrageenan, sodium chondroitin sulfate Brevibacterium sp.No.9605株の生産するγ-CGTaseの性質と利用森茂治 , 大矢隆一 , 北畑寿美雄応用糖質科学 44(2), 185-194, 1997 (CGTase'), starches and maltodextrin are converted into a mixture of cyclodextrins [cyclomalto-oligosaccharides; cyclic (1-+4)-:X-D-glucans;CDs] and non-cyclic malto-oligo saccharides. In the absence of compounds capable of forming inclusion compounds with CDs, the non-cyclic products are normally favoured; overall yields of CD are Amano, Kungsgatan 1, Örebro.
