Enrichment of hepatic glycogen and plasma glucose from H₂18O informs gluconeogenic and indirect pathway fluxes in naturally feeding mice

NMR in Biomedicine, Volume 36, Issue 2, February 2023., 2023
18O‐enrichment of liver glycogen, triglyceride glycerol, and blood glucose of mice given 18O‐water during overnight feeding was quantified by 13C NMR and MS. Glycogen 18O‐enrichment of oxygens 3, 5, and 6 from isotope‐shifted 13C signals informed indirect pathway contributions from different sources.

Unravelling the Mechanistic Pathway of the Hydrogen Evolution Reaction Driven by a Cobalt Catalyst

Angewandte Chemie, Volume 134, Issue 40, October 4, 2022., 2022
A CoI complex bearing a redox‐active κ‐N3P2 pentadentate ligand and its activity towards hydrogen evolution reaction is reported in this work. A combination of spectroscopic, electrochemical and computational techniques is employed to characterize the intermediate species, demonstrating an unusual homolytic coupling reaction pathway between two ...

Cupin‐Type Dimethylsulfoniopropionate Lyase from Pelagibacter ubique (DddKPu) Catalyzes Aza‐Michael Addition of Primary and Secondary Amines to Acrylic Acid

Angewandte Chemie, Volume 137, Issue 45, November 3, 2025.
A dimethylsulfoniopropionate lyase (DddK) was identified as an efficient aza‐Michaelase for the addition of amines to acrylate. Screening 74 amines with wild‐type DddK and its W26G variant yielded N‐substituted and N,N‐disubstituted β‐amino acids in 30%–93% isolated yield.
