Harnessing Photoenzymatic Systems for Intermolecular C–H Fluorination

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Despite the remarkable versatility of enzymes for catalyzing complex organic transformations under mild aqueous conditions, no biocatalytic system has been reported for intermolecular C–H fluorination. A radical photoenzymatic approach is introduced that leverages a designed de novo protein scaffold with an unnatural amino acid to achieve precise ...

Detection Limits of Blood Metabolites at Physiological Concentrations Using Benchtop 1$$ {}^1 $$H NMR

open access: yesNMR in Biomedicine, Volume 39, Issue 2, February 2026.
We demonstrate rapid, sensitive detection of key blood metabolites using an 80 MHz low‐field NMR spectrometer, benchmarking signal‐to‐noise ratios and acquisition efficiency across experimental designs. Millimolar metabolites such as glucose and lactate are reliably detected and quantified within seconds, while simulation‐assisted spectral fitting ...

Deceptive beauty of non‐natural structures

open access: yesProtein Science, Volume 35, Issue 2, February 2026.
Abstract Structures of proteins and multiprotein complexes are considered landmark achievements. However, in many cases, mutant proteins are used for structural work. Even when wild type proteins are used, crystallization or complex formation for cryoEM is performed in highly nonphysiological conditions.
