Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

Advanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron

Angewandte Chemie, EarlyView.
Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Metabolic‐Redox Remodeling of Inflammatory Synovium by Mannose‐Modified Selenium Nanoparticles for Osteoarthritis Therapy

Advanced Science, EarlyView.
Elevated GLUT1‐driven glycolysis and disrupted selenoprotein‐dependent redox homeostasis drive osteoarthritic progression. Intra‐articular mannose‐modified selenium nanoparticles (M‐SeNPs) selectively target hypermetabolic synovial cells to reprogram aberrant glycolysis and restore endogenous antioxidant defenses.

Functional Specialization of Respiratory and Olfactory Mucus Revealed by Proteomic Profiling

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Mucus overlies the nasal mucosa in the respiratory and olfactory regions, which perform distinct physiological functions. However, proteomic differences between respiratory mucosa (RM) and olfactory cleft (OC) mucus remain unclear.

A Ruthenium(CAAC‐5) Olefin Metathesis Catalyst for Bioconjugation

Angewandte Chemie International Edition, EarlyView.
The aqueous instability of ruthenium catalysts restricts olefin metathesis in biological media. A Ru(CAAC‐5) complex bearing an aniline handle is reported that remains active under biologically relevant conditions and enables bioconjugation to proteins, peptides, and an artificial metalloenzyme, providing a robust platform for olefin metathesis in ...
