Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, EarlyView.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Covalent Protein Inhibitors via Tyrosine and Tryptophan Conjugation with Cyclic Imine Mannich Electrophiles

Angewandte Chemie, EarlyView.
Targeted covalent inhibitors (TCI) containing cyclic imine warheads react with tyrosine and tryptophan residues via the Mannich reaction. These cyclic imine warheads show comparable reaction kinetics to cysteine‐reactive electrophiles commonly used in TCIs.

Photoresponsive Rotaxanes Switch Lipid Bilayer Neuromorphic Behavior with Light

Advanced Electronic Materials, EarlyView.
A rotaxane consisting of a macrocycle ring with two azobenzene units mechanically interlocked onto an amphiphilic axle was incorporated into droplet interface bilayers (DIBs). Photoswitching between the azobenzene configurations on the ring resulted in cycling between memristive and memcapacitive behaviors in lipid bilayers, enabling programmable ...

Light‐Driven Competitive Selection in a Protein‐Catalyzed Dissipative Peptide Replication

Angewandte Chemie, EarlyView.
A structurally flexible protein catalyzes replication within a dissipative reaction network driven by UVA‐induced disulfide rearrangements. The protein accelerates templated autocatalytic cycles with replication emerging as the dominant pathway.

Stabilizing Magnesium Anodes in Rechargeable Magnesium Batteries via Fluorinated Cyclic Ether Electrolyte Additive

Advanced Energy Materials, EarlyView.
A fluorinated cyclic ether, FDOL, is shown to stabilize Mg metal anodes by tuning Mg2+ solvation of the G2 electrolyte. The G2‐FDOL electrolyte suppresses passivation and thick, diffusion‐blocking Mg deposits, enabling more uniform Mg plating/stripping and sustained interfacial reactions.

Proximity‐Induced Transfer of a Mass Tag Enables Direct Profiling of Active Matrix Metalloproteases

Angewandte Chemie, EarlyView.
A proximity‐induced, mass‐encoded activity‐based protein profiling (ABPP) approach transfers a MALDI‐detectable α‐cyano‐4‐hydroxycinnamic acid (CHCA) tag directly to active proteases. This tag enables the direct, multiplexed, and quantitative detection of enzyme activity in complex proteomes without enrichment or purification.
