Safety and Modulatory Effects of Humanized Galacto-Oligosaccharides on the Gut Microbiome

Frontiers in Nutrition, 2021
Complex dietary carbohydrate structures including β(1–4) galacto-oligosaccharides (GOS) are resistant to digestion in the upper gastrointestinal (GI) tract and arrive intact to the colon where they benefit the host by selectively stimulating microbial ...

Potential regulation of N-glycosylation precursor through oligosaccharide-lipid hydrolase action and glucosyltransferase-glucosidase shuttle.

Journal of Biological Chemistry, 1991
The potential role of degradative mechanisms in controlling the level of the dolichyl pyrophosphate-linked Glc3Man9GlcNAc2 required for protein N-glycosylation has been explored in thyroid slices and endoplasmic reticulum (ER) vesicles, focusing on cleavage of the oligosaccharide from its lipid attachment and on the enzymatic removal of peripheral ...

Quantitative proteomics reveals the effect of protein glycosylation in soybean root under flooding stress

Frontiers in Plant Science, 2014
Flooding stress has a negative impact on soybean cultivation because it severely impairs growth and development. To understand the flooding responsive mechanism in early stage soybeans, a glycoproteomic technique was used.

Fucosylated Human Milk Oligosaccharides and N-Glycans in the Milk of Chinese Mothers Regulate the Gut Microbiome of Their Breast-Fed Infants during Different Lactation Stages

mSystems, 2018
The milk glycobiome has a significant impact on the gut microbiota of infants, which plays a pivotal role in health and development. Fucosylated human milk oligosaccharides (HMOs) and N-glycans on milk proteins are beneficial for the development of ...

N-Deacetylation of Sinorhizobium meliloti Nod Factors Increases Their Stability in the Medicago sativa Rhizosphere and Decreases Their Biological Activity

Molecular Plant-Microbe Interactions, 2000
Nod factors excreted by rhizobia are signal molecules that consist of a chitin oligomer backbone linked with a fatty acid at the nonreducing end. Modifications of the Nod factor structures influence their stability in the rhizosphere and their biological

Molecular Characterization of an Endo-β-1,4-Glucanase, CelA_J93, from the Recently Isolated Marine Bacterium, Cellulophaga sp. J9-3

Applied Sciences, 2019
A novel cellulase was characterized from a newly isolated marine bacterium, strain J9-3. Phylogenetic analysis based on the 16S rRNA gene revealed that strain J9-3 belonged to the genus Cellulophaga, and thus, it was named Cellulophaga sp. J9-3.

Functional characterization of cellulases identified from the cow rumen fungus Neocallimastix patriciarum W5 by transcriptomic and secretomic analyses

Biotechnology for Biofuels, 2011
Background Neocallimastix patriciarum is one of the common anaerobic fungi in the digestive tracts of ruminants that can actively digest cellulosic materials, and its cellulases have great potential for hydrolyzing cellulosic feedstocks.

A broad pH range and processive chitinase from a metagenome library

Brazilian Journal of Medical and Biological Research
Chitinases are hydrolases that degrade chitin, a polymer of N-acetylglucosamine linked β(1-4) present in the exoskeleton of crustaceans, insects, nematodes and fungal cell walls.

Synthesis and Glycosidase Inhibition Studies of Novel Exoglycals Targeting GH3 Family Enzymes: Insights from Comparative Analysis with Macrolide Antibiotics

Chemistry – A European Journal, EarlyView.
A series of structurally diverse exoglycals was synthesized using a modified Julia‐olefination approach from sugar‐derived precursors. These glycosidase transition‐state mimics were further diversified via CuAAC chemistry to yield triazole‐conjugated analogues.
