SYNTHESES OF COMPLEX OLIGOSACCHARIDE SEQUENCES OF GLYCOCONJUGATES [PDF]

, 2023
The methods of chemically synthesizing complex oligosaccharides have made amazing progress in the past few years. The three basic reactions, especially suited for the selective linking of saccharide units, are characterized. In particular, examples of

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Identifying and characterising a plant GH1 β‐glucosidase that exhibits hydrolytic activity on N‐linked glucopyranoside

FEBS Open Bio, EarlyView.
We report the first β‐glucosidase with demonstrated hydrolytic activity on an N‐linked glycopyranoside. The enzyme, native to maize, was biochemically characterised for this novel reaction, and structural modelling of the enzyme–substrate complex revealed several clues to the underlying reduced catalytic rate relative to its native O‐glycopyranoside ...

Enhanced intracellular Ca(2+) concentrations in Escherichia coli and Bacillus subtilis after addition of oligosaccharide elicitors

, 2011
Elicitation can lead to overproduction of secondary metabolites in plants and microbes. Potential changes in cytosolic Ca(2+) levels in bacteria were studied in response to elicitation.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Effects of High Hydrostatic Pressure on the Distribution of Oligosaccharides, Pinitol, Soysapapogenol A, and Fatty Acids in Soybean

Foods
The effects of high hydrostatic pressure (HHP) treatment (100–600 MPa for 10–60 min) and thermal treatment (boiling for 10–60 min) on oligosaccharides, pinitol, and soyasapogenol A as taste ingredients in soybean (Glycine max (L.) Merr.) (cv. Yukihomare)

Research and Application of Chondroitin Sulfate/Dermatan Sulfate-Degrading Enzymes

Frontiers in Cell and Developmental Biology, 2020
Chondroitin sulfate (CS) and dermatan sulfate (DS) are widely distributed on the cell surface and in the extracellular matrix in the form of proteoglycan, where they participate in various biological processes.
