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

open access: yesAngewandte 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

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

open access: yesAdvanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Salmonella transiently reside in luminal neutrophils in the inflamed gut. [PDF]

open access: yes, 2012
Enteric pathogens need to grow efficiently in the gut lumen in order to cause disease and ensure transmission. The interior of the gut forms a complex environment comprising the mucosal surface area and the inner gut lumen with epithelial cell debris and

Programmable Encapsulation Enables On‐Demand Proliferation of Therapeutic Bacteria for Potent Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A programmable encapsulation technology is developed to reduce bacterial immunogenicity and proliferation after systemic administration. The cross‐linked polymer networks around individual bacteria enable immunogenic shielding and permit selective proliferation in tumors, allowing the bacteria to convert tumor‐accumulated ammonia into L‐arginine and ...

Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

open access: yesAngewandte Chemie, EarlyView.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...
