O2 Activation at an Enzymatic Diiron Site: Bridging Ligand Substitutions Alter Diferric‐(Hydro)peroxo States

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Substituting the bridging carboxylates in diFe sulerythrin shifts the bridging ligand coordination from 1,3‐carboxylate to 1,1‐carboxylate, yielding all three diferrous bridging motifs in one protein. This shortens the Fe–Fe distance and increases reactivity with O2.

Influence of Melt Season Characteristics on Meltwater Partitioning and Delivery Into a Perennial Firn Aquifer

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Perennial firn aquifers in the Greenland ice sheet are known to form and persist in regions of sufficiently high melt rates and accumulation rates throughout the year. However, it is not clear how seasonal to sub‐seasonal variations in surface melt forcings affect the dynamics of melt recharge into a firn aquifer and the accompanying ...

Intra‐ and Intermolecular Glycosylation of d‐Idopyranosyl and 6‐Deoxy‐d‐ido‐heptopyranosyl Donors: Toward the Repeating Unit of Campylobacter jejuni HS:4c Capsular Polysaccharide

European Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
A comprehensive glycosylation study of diversely protected and activated d‐idopyranosyl and 6‐deoxy‐d‐ido‐heptopyranosyl donors using intra‐ and intermolecular coupling strategies is reported. Intramolecular aglycon delivery afforded 1,2‐cis‐β‐idopyranosides, while intermolecular glycosylation yielded chromatographically separable α‐ and β‐linked ...

Boosting Reversible Photocontrol of a Photoxenase by an Engineered Conformational Shift

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Photocontrol of enzymes with photoswitchable unnatural amino acids hitherto yielded only limited light‐regulation factors (LRFs). Here we boosted the LRF of an imidazole glycerol phosphate synthase variant from ∼15 to ∼100 in a semi‐rational design approach and unraveled the mechanistic fundamentals of this effect via biophysical and computational ...

Pure Molecular Inorganic Rings: Mixed Group 14/15 Metallacycles

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
The synthesis and characterization of novel mixed group 14/15 metallacycles incorporating a transition‐metal is described. All of the presented compounds were obtained by reduction of an organometallic Mo2E2 tetrahedrane using Si(I) and Ge(I) compounds, respectively.
