pH‐Responsive Ultrasmall Iron Oxide Nanoassemblies for Activatable T2/T1 Magnetic Resonance Imaging
This research reports a pH‐responsive ultrasmall iron oxide nanoparticle (USIONs)/polymer nanoassemblies for activatable magnetic resonance imaging. Amphiphilic diphosphonic acid block copolymers compactly encapsulate USIONs to generate T2‐weighted contrast at physiological pH, while acidic conditions trigger disassembly, activating T1‐weighted ...

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

Marinocyclins, polycationic macrocyclic depsipeptides, were discovered by genome mining from the marine coral‐derived bacterium Aquimarina megaterium. The compounds have broad‐spectrum activity against gram‐positive and gram‐negative ESKAPE bacteria.

Adenylation Domain Engineering Enables Biosynthesis of an Improved Polymyxin Antibiotic
To enable incorporation of l‐2‐aminodecanoic acid into polymyxin by fermentation, a single Trp‐to‐Ala substitution is rationally introduced into the adenylation‐domain residue of its nonribosomal peptide synthetase (NRPS) and efficiently switches substrate selectivity. The engineered strain produces biologically active Ada‐polymyxin, demonstrating that
