(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

13 Despite their structural similarity with other enzymes in the family catalyzing hydrolysis and/or glycosyl-transfer of α (1→4) and α (1→6)-glycosidic linkages, CGTases have been reported to mainly catalyze α (1→4)-glycosyl transfer reactions. Amano Enzyme was founded 120 years ago in Japan as a pharmaceutical business, expanding into specialty enzymes in 1948 with our first item—malt diastase. Today, we have grown into one of the top enzyme manufacturers, producing enzyme solutions for any industry and every need. Bacillus macerans CGTase, here called Amano, (EC.2.4.1.19) was kindly provided by Amano enzyme Europe Ltd. (Milton Keynes, UK) and Thermoanaerobacter sp. ATCC 53627 CGTase (Toruzyme 3.0L,) from Novozymes (Bagsvaerd, Denmark). Publisher Summary This chapter discusses the purification and action of cyclodextrin-producing enzyme (CGTase).

Today, we have grown into one of the top enzyme manufacturers, producing enzyme solutions for any industry and every need. Bacillus macerans CGTase, here called Amano, (EC.2.4.1.19) was kindly provided by Amano enzyme Europe Ltd. (Milton Keynes, UK) and Thermoanaerobacter sp.

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. To this was added 15 g cyclodextrin glucanotransferase (CGTase, Amano Enzyme Inc., product name: Contizyme, 600 U/mL) and a reaction was started, followed by holding for 24 hours at pH 7.25 and 60° C.

The enzyme was eluted with a linear gradient between 0 and 0.5 M NaCl in Tris–HCl buffer, pH 7.8. CGTase (from Paenibacillus macerans) was purchased from Amano Enzyme Inc. (Aichi, Japan). Glucoamylase (from Rhizopus niv-eus) was purchased from Seikagaku Co. (Tokyo, Japan). All other chemicals used were commercially available and were of analytical grade.

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.

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 The distance of CGTase (EC 2.4.1.19) from Bacillus macerans was purchased from the needle tip from the substrate was varied in the range of 10 Amano Enzyme, Inc. (Japan), and was used without further purifi- to 25 cm. The electrospraying modes were observed using a digi- cation. 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 (Toruzyme 3.0 L) gave a higher yield than that from Bacillus macerans (CGTase Amano).

CGTase solution (1% v/v) and PVA (8 wt%) solution were mixed followed by electrospinning (-9 kV, 3 h). CGTase/PVA nanofibres with an average diameter of 176 ± 46 nm were successfully produced.

Glucoamylase was from Toyobo Co., Ltd. (Osaka, Japan) and B. macerans CGTase was from Amano Enzyme Inc. (Aichi, Japan). The enzyme was further purified using DEAE Sepharose Fast Flow media (Amersham Biosciences Europe GmbH). The enzyme was eluted with a linear gradient between 0 and 0.5 M NaCl in Tris–HCl buffer, pH 7.8.

The synthesis of curcumin oligosaccharides was performed by incubating the reaction mixture (10 mL) containing 0.2 mmol of curcumin d-glucoside, 5 g of soluble starch, and 200 units of CGTase from Bacillus macerans purchased from Amano Pharmaceutical Co. Ltd. in 25 mM sodium phosphate buffer (pH 7.0) at 40 °C for 24 hours. The mixture was centrifuged at 3000 × g for 10 minutes. A combination of one lipase-catalyzed step and one transglycosylation step catalyzed by a cyclodextrin glycosyl transferase (CGTase) was used to synthesize oligosaccharide esters.
