Lysine Oxidation by LOXL2 in Single Strands Versus Triple Helices: Implications for Collagen‐Related Diseases

open access: yesAngewandte Chemie, EarlyView.
The oxidation of Lys residues in proline‐rich single‐stranded collagen by LOXL2, a key enzyme for tissue maturation and linked to diseases, was revealed. Oxidation occurs at rates comparable to or higher than those of Lys in unstructured telopeptides, the well‐known native sites of Lysyl oxidase (LOX) activity.

Activating Triplet Excitons in COFs via Layer‐Bridging Co Single Atoms for Photocatalytic H2O2 Production and Tandem C─N Coupling

open access: yesAngewandte Chemie, EarlyView.
This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

open access: yesAngewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Bioorthogonal Tools for Ethanolamine Lipids and Protein Conjugates

open access: yesAngewandte Chemie, EarlyView.
An alkyne‐tagged ethanolamine analog (AlkEA) enables bioorthogonal, metabolic labeling of endogenous phosphatidylethanolamine (PE) and its protein modifications. AlkEA is incorporated into PE via the Kennedy pathway, allowing CuAAC‐based visualization of PE and affinity capture of PE‐conjugated LC3, ubiquitin, and GPI‐anchored proteins.
