Chemical Proteomics Identifies Ketogenesis‐Mediated Cysteine Modifications Regulating Redox Function

Angewandte Chemie, EarlyView.
Herein, we report ketone body induce cysteine modifications beyond lysine acylation, as revealed by integrating chemical proteomics with open‐search methods. Among the modifications, cysteine crotonation (Ccr) was chemically validated by endogenous peptide‐based co‐elution assays.

From Covalent Traps to Fluorescent Beacons: The Expanding Arsenal of Chemical Probes for Studying Ubiquitin and Ubiquitin‐Like Proteins

Angewandte Chemie, EarlyView.
A large variety of chemistry‐based ubiquitin probes have been developed. ABSTRACT Ubiquitin (Ub) and ubiquitin‐like proteins (Ubls) orchestrate diverse cellular processes through reversible post‐translational modification of target proteins. Their conjugation is governed by a cascade of E1 activating, E2 conjugating, and E3 ligating enzymes, while ...

Aminal‐linked Covalent Organic Frameworks for Light Energy Upconversion

Angewandte Chemie, EarlyView.
Aminal‐linked covalent organic frameworks incorporating anthracene units are introduced as solid‐state platforms for triplet–triplet annihilation upconversion. The crystalline materials retain chromophore electronic properties and exhibit fluorescence quantum yields of up to 40%.
