Cgtase enzyme assay

Assay of enzyme activityThe cyclization activity of CGTase was measured according to the method established by Kaneko et al. with slight modiWcation. The reaction mixture containing 40 mg of soluble starch in 1.0 mL of 0.1 M phosphate buVer (pH 6.0) and 0.1 … 2009-8-5 · CGTase enzyme production levels. Physiological Characterization of CGTase Enzyme Enzyme assay results at different pH conditions ranging from 6.5 to 7.0 are depicted in Fig. 6. Both enzymes (from different sources) showed similar pattern of enzyme activity and indicated parabolic nature. The maximum activity waqs observed at pH 6.7.

Enzyme assays are laboratory methods for measuring enzymatic activity.

28 Nov 2013 Assay of CGTase activity. The CGTase activity of the free and immobilized enzyme was measured as the β-CD forming activity in accordance

# 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 CGTase (vollständige Bezeichnung: Cyclodextringlucanotransferase) verknüpft Traubenzucker () zu ringförmigen Cyclodextrinen. CGTase wird in der Stärkeindustrie zur Herstellung von Cyclodextrinen () eingesetzt. Assay of CGTase was carried out according to the method of Kaneko et al., 1987 [2].

The cyclization activity of CGTase: Enzyme assay was carried out according to the method of Kaneko (1987). After incubation for 24 to 48 h, the culture was centrifuged at 5000 rpm for 2 min. Crude enzyme solution (0.5ml) was added to 1.0 ml of 0.04 g soluble starch in 1.0 ml of phosphate buffer (pH 6.0).

Cyclodextrin glycosyltransferase (CGTase) is an enzyme able to convert starch and other substrates into cyclodextrins (CDs). Enzyme assays can be split into two groups according to their sampling method: continuous assays, where the assay gives a continuous reading of activity, and discontinuous assays, where samples are taken, the reaction stopped and then the concentration of substrates/products determined.
