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

Molecular Engineering of a Mixed‐Spacer System Toward High‐Performance Polycarbazole Anion‐Exchange Membranes

Angewandte Chemie, EarlyView.
Mixed‐spacer polycarbazole membranes balance conductivity, swelling, and stability by tuning hydration and ionic connectivity. The optimized membrane reaches 184 mS cm−1 hydroxide conductivity and 2.51 W cm−2 peak power density, offering a promising strategy for high‐performance ether‐free AEMs.

Agostic Hydridoborate Complexes as Masked Coinage‐Metal Hydrides: Hydride Migration Between Boron and Gold Unlocks CO2 Reactivity

Angewandte Chemie, EarlyView.
Hydride addition to coinage‐metal diphosphine–borane complexes gives unprecedented Cu(I), Ag(I), and Au(I) hydridoborates featuring agostic σ(B–H)→M interactions. While, Cu and Ag derivatives are inert toward CO2, the Au analogue reversibly fixes CO2 and catalyzes its hydroboration as well as formic acid dehydrogenation through a cooperative B─H─Au ...

S = 3/2 Iron(I)‐Bisphosphine‐Ate Complexes: Synthesis, Characterization, and Reactivity for Electrophile Activation

Angewandte Chemie, EarlyView.
In this work, we present a new class of unusual charged Fe(I)‐bisphosphine‐ates, along with full characterization of their structure and bonding, utilizing low‐temperature synthetic and spectroscopic and techniques. These complexes are highly reactive toward catalytically relevant electrophiles, and can serve as valuable synthons providing access to ...

The Nature of Cell‐Penetrating Poly(disulfide)s

Angewandte Chemie, EarlyView.
The mode of action of cell‐penetrating poly(disulfide)s (CPDs) is elucidated to understand thiol‐mediated uptake (TMU) in general and guide future efforts to control cellular entry for chemicals delivery and pathogen defense. ABSTRACT Cell‐penetrating poly(disulfide)s (CPDs) are the most popular thiol‐mediated uptake (TMU) tools for delivering attached

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐
