Molecular Details of RNA Interactions With FUS Condensates Altering Assembly, Dynamics, and Aggregation

Angewandte Chemie, EarlyView.
Using NMR and molecular simulations, we map how RNA engages FUS LC‐RGG1 within condensates through electrostatic, π‐stacking, and polar contacts. These multivalent RNA contacts help stabilize RNA within FUS condensates while also reshaping condensate composition and dynamics.

Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer

Angewandte Chemie, EarlyView.
A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.

Ag─S Sites Steer Furfural Electroreduction to Furfuryl Alcohol

Angewandte Chemie, EarlyView.
A simple sulfide incorporation strategy turns silver into a highly active and selective catalyst for furfural electroreduction to furfuryl alcohol. Experiments combined with density functional theory reveal how isolated S sites promote hydrogenation while suppressing hydrofuroin coupling, enabling selective biomass upgrading.

Modifications of Lysine Residues 294 and 311 Within the Microtubule‐Binding Region Alter Tau Aggregation and Tubulin Binding Equilibria

Angewandte Chemie, EarlyView.
The molecular consequences of specific lysine modifications in Alzheimer´s disease remain insufficiently resolved in the context of full‐length protein. Here we integrate protein semisynthesis, segmental isotope labelling, and high‐resolution NMR spectroscopy to achieve residue‐resolved interrogation of site‐specific acetylation and carboxymethylation.
