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

A Novel Immunosuppressive Effector Functions as a Bio‐Adjuvant to Enhance the Activity of Bacillus Thuringiensis and Chemical Insecticides

Advanced Science, EarlyView.
A previously unrecognized link between quorum sensing and host immune suppression is revealed in Bacillus thuringiensis(Bt). The PlcR‐PapR system induces the novel immunosuppressive effector PisP, which inhibits DAF‐16 nuclear translocation and downstream immune defenses, thereby promoting Bt pathogenicity.

Magnetic Resonance Reveals Radical Stability in Native Biofilms and Its Role in Bacterial Resistance

Angewandte Chemie, EarlyView.
The complex biofilm environment consists of planktonic bacterial cells and cells embedded in an extracellular matrix (ECM). Through an integrated magnetic resonance approach, we show that nitroxide radicals primarily interact with the polysaccharides and lipids in the ECM.

Next Generation Antimicrobial Coatings for High Touch Surfaces: Application, Benefits, Risks, Environmental Impacts and Sustainability Aspects

Advanced Science, EarlyView.
Antimicrobial coatings for high touch surfaces promise infection control but are too often validated only in the lab. This review shows that active‐agent release governs both human toxicity and environmental impact and argues that durability and real‐world performance must be primary design criteria, placing a safe‐and‐sustainable‐by‐design framework ...

SUMOylated DDX3 Promotes HBV Replication and Tumor Growth of Hepatocellular Carcinoma via TRIM28‐DDX3‐KLF4α Signaling Axis

Advanced Science, EarlyView.
TRIM28 binds to DDX3 protein to catalyze the SUMOylation of DDX3 (S‐DDX3), thus the S‐DDX3 involves in aberrant alternative splicing of KLF4 mRNA, and the splicing variant KLF4α‐mediated cell cycle and signal transduction, weakens tumor suppressor function of DDX3 protein, which promotes progression of HBV‐HCC.
