This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. CGTase, was selected from B. cereus YUPP-10 by a constructed fos-mid library. We discovered that CGTase has antimicrobial activity and induces resistance. In addition, we have revealed the key do-mains responsible for its hydrolytic activity and resistance induction.

概要. The cyclodextrin glycosyltransferase (CGTase, EC 2.4.1.19) gene from Bacillus circulans strain 251 was cloned and sequenced. It was found to code for a mature protein of 686 amino acid

この澱粉中に存在するグルコシド結合を特異的に加水分解する、あるいは転移反応により合成する酵素は以下の4つ 2009-07-08 · Activity characteristics and kinetic aspects of a cyclodextrin glycosyltransferase (CGTase) from Bacillus circulans DF 9R were studied.

CGTase / sucrose ester / glycosyl transfer reaction / glucose / surfactant / lauric acid / sucrose laurate / non-ionic surfactant: 研究概要: CGTaseはデキストリンから水酸基への糖転移を触媒するが、これまでの実施例から、その水酸基結合する化合物が比較的水溶性が高い事が重要である。 The novel CGTase (CspCGT13) was also subjected to multiple sequence alignment with other well-characterized CGTases. From the alignment, the CGTase-specific sequence conservation was found in the four conserved regions identified for amylolytic enzymes (regions I, II, III and IV) (Table II) (MacGregor et al.

In addition, we have revealed the key do-mains responsible for its hydrolytic activity and resistance induction. Further experiments demonstrated that CGTase is a potential func - 2014-12-15 CGTase has, in addition to its C-terminal CBM20 domain, an N-terminal catalytic domain belonging to glycosyl hydrolase family 13 and an IPT domain of unknown function. The CBM20 domain is found in a large number of starch degrading enzymes including alpha-amylase, beta-amylase, glucoamylase, and CGTase (cyclodextrin glucanotransferase). 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.

The CGTase residue has a C-alpha atom located < 6 Å from a heavy atom (i.e., an atom other than H) of an amino acid residue of the maltogenic alpha-amylase corresponding to residue 190-194 of SEQ ID NO: 17. The CGTase residue is in a subsequence (a "loop") of the CGTase … 2014-03-13 2020-03-18 cgtase bacteria cyclodextrin gene starch Prior art date 1990-03-27 Application number PCT/EP1991/000560 Other languages German (de) French (fr) Other versions WO1991014770A3 (en Inventor Gerhard Schmid Original Assignee Consortium für elektrochemische Industrie GmbH Priority date (The priority date is an assumption and is not a legal conclusion. For CGTase this mechanism can easily be imagined with the aid of a maltononaose substrate bound in the active site , as derived from the X‐ray structure of the enzyme complexed with a maltononaose inhibitor []. From this complex, either a cyclization or a disproportionation reaction can … 2016-11-01 CGTase activity decreased 20 fiold when incubation temperature was increased from 28 to 37 degreesC, and decreased 2.1- fold when the initial pH was lowered from 10.3 to 7.4. 2012-12-12 CDは,澱 粉にシクロデキストリン合成酵素.

It was found to code for a mature protein of 686 amino acid residues, showing 75% identity to the CGTase from B. circulans strain 8. CGTase, also known as cyclodextrin glycosyltransferase and cyclodextrin glucanotransferase, catalyzes the formation of various cyclodextrins (alpha-1,4-glucans) from starch. CGTase has, in addition to its C-terminal CBM20 domain, an N-terminal catalytic domain belonging to glycosyl hydrolase family 13 and an IPT domain of unknown function. The type of CGTase producer can be classiWed as -CGTase, -CGTase or -CGTase, depending on the major type of CD produced by the CGTase reaction. All wild type CGTases are able to produce -CD, however typically it is produced as part of a mixture of CDs. An identical experiment with the CGTase from T. thermosulfurigenes EM1 resulted in a 2.6-A resolution x-ray structure of a complex with a maltohexaose inhibitor, bound in a different conformation. We hypothesize that the new maltohexaose conformation is related to the enhanced alpha-cyclodextrin production of the CGTase. 2021-02-20 · CGTase from different microorganisms has different numbers of residues in 5 domains (A-E).
