Structural genomics analysis of uncharacterized protein families overrepresented in human gut bacteria identifies a novel glycoside hydrolase. [PDF]

open access: yes, 2014
BackgroundBacteroides spp. form a significant part of our gut microbiome and are well known for optimized metabolism of diverse polysaccharides. Initial analysis of the archetypal Bacteroides thetaiotaomicron genome identified 172 glycosyl hydrolases and

Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

open access: yesChemistry – A European Journal, EarlyView.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate

open access: yesChemPhysChem, EarlyView.
Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

3,4,6-Tri-O-acetyl-1-S-acetyl-2-deoxy-2-S-phenylthio-α-d-mannopyranoside

open access: yesMolbank
The title compound was isolated as the unexpected reaction product from a reaction attempting to access a glycosyl 1-phosphate. The product was isolated in good yield, as one diastereoisomer, and was characterised by 1H, 13C, and 2D NMR, alongside HRMS ...

Carbonylative Suzuki–Miyaura Coupling of 1‐Iodoglycals Mediated by the N‐Heterocyclic Carbene Catalyst PEPPSI: Preparation of C‐Acyl Glycosides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...

Predicting the substrate specificity of a glycosyltransferase implicated in the production of phenolic volatiles in tomato fruit [PDF]

open access: yes, 2011
The volatile compounds that constitute the fruit aroma of ripe tomato (Solanum lycopersicum) are often sequestered in glycosylated form. A homology-based screen was used to identify the gene SlUGT5, which is a member of UDP-glycosyltransferase 72 family ...

Metabolic profile, bioavailability and toxicokinetics of zearalenone-14-glucoside in rats after oral and intravenous administration by liquid chromatography high-resolution mass spectrometry and tandem mass spectrometry [PDF]

open access: yes, 2019
Zearalenone-14-glucoside (ZEN-14G), a key modified mycotoxin, has attracted a great deal of attention due to the possible conversion to its free form of zearalenone (ZEN) exerting toxicity.
