An IscS Persulfide Donates the Sulfur for Ribosomal Protein uL16 Thioamidation

Angewandte Chemie, EarlyView.
YcaO‐catalyzed thioamidation of the ribosomal subunit protein uL16 is widespread in Pseudomonadota bacteria. We identify the iron–sulfur cluster cysteine desulfurase IscS as the sulfur donor via an IscS persulfide and observe direct IscS–uL16 interactions.

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

Bromide–Borate Coupling Enables Selective Electrochemical Oxidation of Glycerol to Dihydroxyacetone

Angewandte Chemie, EarlyView.
Bromide–borate coupling enables selective electrochemical upgrading of glycerol to dihydroxyacetone (DHA). Electrogenerated bromine species mediate glycerol oxidation, while borate coordination biases selectivity toward DHA, enabling carbon‐balanced oxidation and high productivity in flow‐cell operation.

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.
