Retrieval and analysis of nucleotide sequence encoding the CGTase enzyme Genomic DNA of thermophilic bacterial isolates from a strain collection at Matis Ltd. in Iceland was screened for cyclodextrin glucanotransferase (CGTase) encoding sequences in a PCR-based experiment. 2018-08-03 · The current method is based on the concept of establishing a simple assay of catalase enzyme activity for biological tissues, which depends on the conversion of the oxidation state of cobalt (II) to cobalt (III) by hydrogen peroxide in the presence of bicarbonate solution. Cyclodextrin glycosyltransferase (CGTase) is an enzyme able to convert starch and other substrates into cyclodextrins (CDs).

γ-Cyclodextrin glycosyltransferase (γ-CGTase) catalyzes the biotransformation of low-cost starch into valuable γ-cyclodextrin (γ-CD), which is widely applied in biotechnology, food, and pharmaceutical industries.

I-5 (CGTase I-5). A mutant CGTase [3-18] with the three mutations M234T, F259I and V591A was selected by agar plate assay. CGTase enzyme assay.

Can I still use it in an assay? Answer 1: Yes, Cytoskeleton offers the EasyRad Phosphate Assay Biochem Kit (Cat. # BK055) that is specifically designed for low activity GTPases. The kit is a simple two step assay based on the separation of 32 or 33 Phosphate from 32 or 33 Gamma-Phosphate-Nucleoside

cyclomaltodextrin glucanotransferase (CGTase, EC 2.4.1.19). The CDs can be quantified by chromatography, i.e., HPLC [1, 4,5] or by their ability to form inclusion complexes [2,3,6-8]. P-CD is γ-Cyclodextrin glycosyltransferase (γ-CGTase) catalyzes the biotransformation of low-cost starch into valuable γ-cyclodextrin (γ-CD), which is widely applied in biotechnology, food, and pharmaceutical industries. Cyclodextrin glucanotransferase (CGTase; EC 2.4.1.19) is a unique member of glycoside hydrolase family 13. Its defining property is the ability to form cyclodextrins from starch, through an intramolecular transglycosylation reaction (cyclization). CGTase Enzyme Assay CGTase activity was determined using the phe-nolphthalein assay as described by Kaneko et al., (1987). The assay was performed by adding 0.1 mL of the sample to CGTase assay reagent containing 1 mL of 0.04 g soluble starch in 0.1 M phosphate buffer, pH 6.0.

One unit of CGTase activity was defined as the amount of enzyme releasing one µmol of β-CD per min under the defined assay conditions. A calibration curve

Double-stranded DNA activates the enzyme which generates cGAMP in the presence of both GTP and ATP. A 45 base pair ISD (interferon stimulatory DNA) and a 60 base pair HSV (herpes simplex virus) DNA both activate the enzyme.
