Glucosylation of sucrose laurate with cyclodextrin glucanotransferase.
Sucrose monolauroyl esters were found to serve as substrates for cyclodextrin glucanotransferase (CGTase)-catalyzed transglucosidation reactions, affording new sucrose esters that have an additional 1-3 glucose residues on the pyranose ring of the sucrose moiety in the ester.
متن کاملProduction of Hesperetin Glycosides by Xanthomonas campestris and Cyclodextrin Glucanotransferase and Their Anti-allergic Activities
The production of hesperetin glycosides was investigated using glycosylation with Xanthomonas campestris and cyclodextrin glucanotransferase (CGTase). X. campestris glucosylated hesperetin to its 3'-, 5-, and 7-O-glucosides, and CGTase converted hesperetin glucosides into the corresponding maltosides. The resulting 7-O-glucoside and 7-O-maltoside of hesperetin showed inhibitory effects on IgE a...
متن کاملRegioselective glucosylation of pyridoxine by microorganisms.
Microorganisms from culture collections and isolates from nature were screened for the ability to catalyze the regioselective glucosylation of pyridoxine (PN) to produce pyridoxine 5'-alpha-D-glucoside (PN-5'-alpha-G) or pyridoxine 4'-alpha-D-glucoside (PN-4'-alpha-G). Transglucosylation activity specific to 5'-position of PN was found in fungi belonging to genera such as Coriolus and Verticill...

Crystallization and preliminary X-ray diffraction studies of Tyr167His mutant α-cyclodextrin glucanotransferase from Bacillus macerans.
Improving the specificity of α-cyclodextrin glucanotransferase is a significant issue in the field of α-cyclodextrin production. In this study, a constructed Y167H mutant α-cyclodextrin glucanotransferase with enhanced α-cyclodextrin specificity was successfully expressed and purified. Single crystals were grown using PEG 4000 as a precipitating agent by the hanging-drop vapour-diffusion method...
