Structural and functional characterization of chitinase from carnivorous plant Drosera adelae

open access: yesFEBS Open Bio, EarlyView.
A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.

Decoding a Gut Commensal Signal: Structural and Immunological Profiling of Segatella Copri Lipopolysaccharide

open access: yesAngewandte Chemie, EarlyView.
The lipopolysaccharide (LPS) of Segatella copri is a structurally unique, immunomodulatory glycoconjugate. Combining mass spectrometry (MS), nuclear magnetic resonance (NMR), and cytometry by time‐of‐flight (CyTOF), we uncover a rough‐type LPS with reduced TLR4 agonism and selective monocyte effects, further highlighting the key role of LPS chemistry ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Iron‐Catalyzed Highly Stereospecific Glycosylation with Glycal Epoxides

open access: yesAngewandte Chemie, EarlyView.
We report an iron‐catalyzed, highly stereospecific glycosylation method with glycal epoxides, which is effective for a broad range of substrates, including previously challenging, sterically hindered secondary acceptors and glucuronic ester epoxide donors.

Thiolated Hyaluronic Acid: A Gateway for Targeted Killing of Staphylococcus aureus on the Race for Surface Colonization

open access: yesAdvanced Healthcare Materials, EarlyView.
Thiolated hyaluronic acid (HAMS) synthesized and characterized by NMR, solubility, thiol content, and pKa, is degraded by Staphylococcal hyaluronate lyase but not by mammalian hyaluronidase. Coating polyphosphate–M23 phage endolysin nanoparticles (M23‐PP) with HAMS confers Staphylococcus aureus responsiveness.

Glucosamine protects against neuronal but not vascular damage in experimental diabetic retinopathy

open access: yesMolecular Metabolism, 2021
Objective: Glucosamine, an intermetabolite of the hexosamine biosynthesis pathway (HBP), is a widely used nutritional supplement in osteoarthritis patients, a subset of whom also suffer from diabetes. HBP is activated in diabetic retinopathy (DR).
