Transcriptomic Studies Reveal that the Rhizobium leguminosarum Serine/Threonine Protein Phosphatase PssZ has a Role in the Synthesis of Cell-Surface Components, Nutrient Utilization, and Other Cellular Processes [PDF]

open access: yes, 2019
Rhizobium leguminosarum bv. trifolii is a soil bacterium capable of establishing symbiotic associations with clover plants (Trifolium spp.). Surface polysaccharides, transport systems, and extracellular components synthesized by this bacterium are ...

Synthesis of Rhamnose‐Modified Lewis‐X‐Containing Saponins

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The synthesis of triterpenoid saponins bearing a Lewis‐X trisaccharide analogue, in which the fucose residue is replaced by a rhamnose, is presented. These saponins, designed as negative controls in dendritic cell‐specific intercellular adhesion molecule‐3‐grabbing nonintegrin‐targeted therapeutic applications, are prepared through iterative and ...

Quasi-Steady-State Approach for Efficient Multiscale Simulation and Optimization of mAb Glycosylation in CHO Cell Culture [PDF]

open access: yesarXiv
Glycosylation is a critical quality attribute for monoclonal antibody (mAb) production, influenced by both process conditions and cellular mechanisms. Multiscale mechanistic models, spanning from the bioreactor to the Golgi apparatus, have been proposed for analyzing the glycosylation process.

New Glycoconjugates Containing Selenium and Polyphenols. Stereoselective Synthesis by Pummerer‐like Rearrangement.

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Two series of novel six‐membered Se‐glycoconjugates containing hydroxycinnamic acids marked by well‐known antioxidant properties are synthesized, exploiting a Mitsunobu reaction and a Pummerer‐like rearrangement. A first example of six‐membered selenosugar with selenium in the ring and bearing an acetal‐like functional group at C‐1 was reported, which ...

Structural Characterization, Phenolic Acid Modification, and Antioxidant Activities of Polysaccharide From Mogroside Waste Liquid of Siraitia grosvenorii

open access: yesFood Frontiers, EarlyView.
ABSTRACT To improve the comprehensive utilization of Siraitia grosvenorii (Swingle) C. Jeffrey, a novel polysaccharide (SGP) was isolated from the mogroside waste liquid of S. grosvenorii. In addition, ferulic acid–SGP (FA‐SGP) and caffeic acid–SGP (CA‐SGP) were prepared by modifying SGP with phenolic acid.

Duckweed: Growth factor and applications in nonfood, food, and health

open access: yesFood Safety and Health, Volume 3, Issue 2, Page 144-154, April 2025.
Versatile Duckweed! Duckweeds are aquatic plants that are mainly constituted of five genera, Lemna, Spirodela, Wolffia, Wolffiella, and Landoltia. The growth rates and chemical compositions are influenced by light intensity, photoperiod, nutrient content, microbial growth, temperature, medium salinity and conductivity, windspeed, climate, and water pH.

Blue Fluorescent Chlorophyll Catabolites from Banana Leaves Hypermodified with Terpenoidic Groups Related to Abscisic Acid

open access: yesHelvetica Chimica Acta, EarlyView.
Abstract In senescent leaves of banana (Musa acuminata) hypermodified fluorescent chlorophyll (Chl) catabolites (hmFCCs) accumulate and give these leaves an easily observable blue fluorescence. Non‐fluorescent Chl‐catabolites (NCCs) are not detected, the typical colourless Chl‐catabolites that accumulate in most de‐greened plant leaves. Here, we report
