A glucotolerant β-glucosidase from the fungus Talaromyces amestolkiae and its conversion into a glycosynthase for glycosylation of phenolic compounds

Microbial Cell Factories, 2020
Background The interest for finding novel β-glucosidases that can improve the yields to produce second-generation (2G) biofuels is still very high. One of the most desired features for these enzymes is glucose tolerance, which enables their optimal ...

Glycoside Hydrolases for Extraction and Modification of Polyphenolic Antioxidants [PDF]

, 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 glycosylated forms in many natural resources, can be extracted and modified using glycoside hydrolases ...

Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]

, 2015
MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

Artificial intelligence‐assisted design, synthesis and analysis of smart biomaterials

BMEMat, EarlyView.
Smart biomaterials are rapidly emerging as tools for tissue engineering, and artificial intelligence has played essential roles in biomaterial studies. By bridging the literature gap in AI‐based design, synthesis and analysis of smart biomaterials, the current review shares perspectives on how biomaterial scientists can practically incorporate AI for ...

Inverting family GH156 sialidases define an unusual catalytic motif for glycosidase action

Nature Communications, 2019
Sialidases are glycoside hydrolases that cleave sialosides. Here the authors define the 3-D structure, alone and in complex with products and inhibitors, of the CAZy family GH156 sialidase, EnvSia156, showing it displays a catalytical (β/α) 8-barrel ...

Pharmacokinetic Prediction and Cytotoxicity of New Quercetin Derivatives

Chemistry &Biodiversity, EarlyView.
ABSTRACT Quercetin (QUE) possesses various pharmacological properties; however, its low bioavailability and solubility hinder its beneficial effects. Enzymatic glycosylation has been explored to improve these aspects. In the present study, we used a sucrose phosphorylase variant to catalyze the regioselective transglucosylation of QUE, predicted the ...

Amylases and related glycoside hydrolases with transglycosylation activity used for the production of isomaltooligosaccharides

Amylase, 2018
Isomaltooligosaccharides (IMOS) are sugars with health promoting properties that make them relevant for the pharmaceutical and food industries. IMOS have ample chemical diversity achieved by different α-glucosidic linkages and polymerization degrees ...

Host-linked soil viral ecology along a permafrost thaw gradient [PDF]

, 2018
Climate change threatens to release abundant carbon that is sequestered at high latitudes, but the constraints on microbial metabolisms that mediate the release of methane and carbon dioxide are poorly understood1,2,3,4,5,6,7.

The mucin-degradation strategy of Ruminococcus gnavus:The importance of intramolecular trans-sialidases [PDF]

, 2016
We previously identified and characterized an intramolecular trans-sialidase (IT-sialidase) in the gut symbiont Ruminococcus gnavus ATCC 29149, which is associated to the ability of the strain to grow on mucins. In this work we have obtained and analyzed
