Cyclodextrin glycosyltransferases (CGTases) from Paenibacillus macerans, Thermoanaerobacter sp. ATCC 53627, Bacillus stearothermophilus and a Carboxydocella sp. (phylogenetically identified from genomic DNA) were characterized with respect to their catalytic activity in different reactions, with emphasis on reactions useful for the elongation of the carbohydrate group of alkyl glycosides.

Resveratrol 3-maltoside (8) and resveratrol 4′-β-maltoside (9) were produced individually as fol-lows. To a solution containing resveratrol 3-β-glucoside (2) or resveratrol 4′-β-glucoside (3) (0.1mmol) and (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 Enzymatic glycosylation of curcumin 4‘-O-β-D-glucopyranoside (2) with CGTase afforded curcumin 4‘-O-β-glucooligosaccharides .

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.

The crude CGTase extract with the corn starch substrate showed a productivity of 0.38 mmol/L/h, which was 29 % lower than using the purified enzyme and the corn starch substrate but 7 % higher

These enzymes have been 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. BM CGTase was obtained from Amano Enzyme Inc. (Aichi, Japan) and had a specific activity of 1003 U·mg −1 of dextrinizing activity []. A11 CGTase was purified using starch adsorption and ion exchange chromatography (DEAE‐Toyopearl 650M column; Tosoh Corporation, Tokyo, Japan). CGTase could be successfully immobilised into a nanofibrous polyvinyl alcohol (PVA) membrane (Saallah et al., 2016) by co-electrospinning of CGTase and PVA mixture, which allow the enzyme to attach andencapsulatedinthenanofibers.ThePVAsolution is rich with hydroxyl groups that enable the formation of secondary bonding with the enzyme molecules. 1996-01-01 · CGTase, which produces mainly ~-CD, seems to exist widely.

Glucoamylase (from Rhizopus niv-eus) was purchased from Seikagaku Co. (Tokyo, Japan). All other chemicals used were commercially available and were of analytical grade. Medium. 500 mL water and then 40 g corn starch were added to 10 g of the IQC obtained as described above and a dispersion was prepared.
