Microbial Cyclodextrin Glycosyltransferases: Sources, Production, and Application in Cyclodextrin Synthesis

Catalysis Research, 2022
Cyclodextrin glycosyltransferase (CGTase) is a multifunctional enzyme that hydrolyzes the <em><i>&alpha;</i></em>-glycosidic bond between two sugar molecules and synthesizes cyclodextrins (CDs) and other transglycosylation products.

Cyclic β-glucans at the bacteria–host cells interphase: One sugar ring to rule them all [PDF]

, 2018
Cyclic β‐1,2‐D‐glucans (CβG) are natural bionanopolymers present in the periplasmic space of many Proteobacteria. These molecules are sugar rings made of 17 to 25 D‐glucose units linked exclusively by β‐1,2‐glycosidic bonds.

Glycemic Response to Corn Starch Modified with Cyclodextrin Glycosyltransferase and its Relationship to Physical Properties [PDF]

, 2016
Corn starch was modified with cyclodextrin glycosyltransferase (CGTase) below the gelatinization temperature. The porous granules with or without CGTase hydrolysis products may be used as an alternative to modified corn starches in foods applications ...

Isolation of alkalophilic CGTase-producing bacteria and characterization of cyclodextrin-glycosyltransferase

Brazilian Archives of Biology and Technology, 2003
One hundred and twenty five soil samples were collected from the regions of roots of corn, cassava, potato, bean, sugar cane, soya, and pumpkin. From these, 75 strains were isolated that produced a yellowish halo surrounding the colonies, due to a ...

One-Pot Hetero-Di-C-Glycosylation of the Natural Polyphenol Phloretin by a Single C-Glycosyltransferase With Broad Sugar Substrate Specificity. [PDF]

Biotechnol Bioeng
Here, an efficient system for synthesizing high‐value polyphenol hetero‐di‐C‐glycosides with two distinct C‐glycosyl residues was established using a two‐step glycosylation catalyzed by C‐glycosyltransferase in one pot. The desired C‐β‐galactosyl‐C‐β‐glucosyl and C‐β‐glucosyl‐C‐β‐xylosyl phloretin were obtained at concentrations of 0.6 and 6 g/L ...
