Modification and application of glycosidases to create homogeneous glycoconjugates [PDF]

open access: yes, 2013
In the post-genomic era, recognition of the importance of sugars is increasing in biological research. For the precise analysis of their functions, homogeneous materials are required.

A Glycosynthase Catalyst for the Synthesis of Flavonoid Glycosides

open access: yesAngewandte Chemie International Edition, 2007
Glycosylation of lipophilic small molecules is one of the predominant strategies by which the bioactivity of these compounds is modulated in living organisms. Indeed, even simple plants, such as Arabidopsis thaliana, dedicate over 120 open reading frames encoding many activated sugar-dependent glycosyltransferases to this task alone.

Glycoside hydrolases for extraction and modification of polyphenolic antioxidants [PDF]

open access: yes, 2013
Antioxidants are important molecules that are widely used by humans, both as dietary supplements and as additives to different types of products. In this chapter, we review how flavonoids, a class of polyphenolic antioxidants that are often found in ...

A front-face 'SNi synthase' engineered from a retaining 'double-SN2' hydrolase. [PDF]

open access: yes, 2017
SNi-like mechanisms, which involve front-face leaving group departure and nucleophile approach, have been observed experimentally and computationally in chemical and enzymatic substitution at α-glycosyl electrophiles.

Pretreatment and enzyme hydrolysis of canola meal (Brassica napus L.) and oriental mustard bran (Brassica juncea): production of functional oligosaccharides and impact on phenolic content [PDF]

open access: yes, 2014
Canola meal (Brassica napus L.) and oriental mustard bran (Brassica juncea) were subjected to alkali and acid pretreatment to expose pentosan, for enhancing further enzymatic hydrolysis by endo-1,4-β-xylanase from Trichoderma longibrachiatum for the ...
