ChemBioChem, EarlyView.This analysis reveals structural heterogeneity in the lipopolysaccharide lipid A from the cold‐adapted Gram‐negative bacterium Polaribacter sp. SM1127, with variations in fatty acid chain number, length, branching, saturation, and hydroxylation degree, likely aiding bacterial adaptation to cold environmental stressors. Lipopolysaccharide is shown to be

Genomewide and Enzymatic Analysis Reveals Efficient d-Galacturonic Acid Metabolism in the Basidiomycete Yeast Rhodosporidium toruloides. [PDF]
, 2019 Biorefining of renewable feedstocks is one of the most promising routes to replace fossil-based products. Since many common fermentation hosts, such as Saccharomyces cerevisiae, are naturally unable to convert many component plant cell wall ...

A Biocatalytic Cascade for the Valorization of Sugars
ChemCatChem, EarlyView.We report a one‐pot, three‐step biocatalytic cascade to synthesize trihydroxy‐piperidine and ‐azepane iminosugars directly from monosaccharides, employing transaminase (ATA) and galactose oxidase (GOase) enzymes. Abstract Biocatalytic cascades offer products of multistep synthesis without the use of protecting groups or isolation of intermediates. This

ChemCatChem, EarlyView.Three series of titania–Cu photocatalysts have been prepared and tested for hydrogen generation by cellulose photo‐reforming. Copper was incorporated, by impregnation, in P25 (a) and in hydrothermally synthesized TiO2 (b), and also by a one‐pot hydrothermal synthesis (c).

ChemElectroChem, EarlyView.This study analyzes the electrochemical reduction pathways of 5‐hydroxymethylfurfural (HMF) on Cu electrodes. Our findings show that 2,5‐bis(hydroxymethyl)furan (BHMF) and 5‐methylfurfural (5‐MF) occurs through direct HMF reduction. Additionally, 5‐methylfurfural alcohol (MFA) can be produced either from HMF or 5‐MF, while 2,5‐dimethylfuran is derived ...

Chemistry – A European Journal, EarlyView.We designed and synthesized novel mannose‐6‐phosphate (M6P) derivatives to enhance their binding affinity for the CI‐M6P/IGF2 receptor, which plays a key role in lysosomal targeting. Using a fluorescence polarization assay, we evaluated di‐, tri‐, and penta‐M6P peptides and modified M6P analogs.

Chemistry – A European Journal, EarlyView.The convergent synthesis of Lewis‐X‐containing betulinic acid and echinocystic acid saponins (1 and 2) is presented. The synthetic saponins were shown to inhibit, at the low micromolar range, the DC‐SIGN‐ and L‐SIGN‐mediated transfer of HIV‐1 infection to CD4‐positive cells, whereas free Lewis‐X, aglycones, and structurally similar triterpenoid ...

The development of a purification procedure for Peptide:n-Glycosidase A from Prunus amygdalus : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Biochemistry at Massey University [PDF]
, 1997 Peptide-N4-acetyl-β-glucosaminyl) asparagine amidases cleave the amide bond between N-linked glycans at N-acetylglucosamine and asparagine, liberating intact oligosaccharide chains from glycoproteins. Although PNGase A is commonly used by glycobiologists

The Synthesis of Aryl‐β‐C‐Glycosides from Native Saccharides
Chemistry – A European Journal, EarlyView.Native mono‐, di‐, and trisaccharides are converted into p‐nitrophenol‐β‐C‐glycosides in a one‐pot reaction using water as the solvent. A sequence of condensation reactions is used to construct the aromatic ring from acyclic precursors. Using this approach, a modular synthesis of SGLT2‐inhibitor scaffolds was developed and applied to a novel protecting‐
