Protein Structuromics Reveals a Loop‐Controlled Half‐Open Active Pocket Conformation Throughout Fe(II)/α‐ketoglutarate‐Dependent Dioxygenase Catalytic Cycle

Advanced Science, EarlyView.
This study reveals a conserved half‐open active pocket in Fe(II)/α‐ketoglutarate‐dependent dioxygenases through protein structuromics, distinguished by structural features comprising highly flexible loop elements. Enhanced sampling simulations‐guided mutagenesis experiments elucidated how this flexible loop regulates pocket open/closed conformations ...

Spin‐Selective Oxygen Evolution in Chiral Molecule‐Intercalated Layered Double Hydroxides

Advanced Science, EarlyView.
This hybrid electrocatalyst utilizes chiral phenylalanine intercalation within layered double hydroxides to boost oxygen evolution. Acting as a spin filter via the chiral‐induced spin selectivity effect, the material directs electron transfer along a lower‐energy pathway.

Giant Topological Hall Effect Across a Broad Temperature Window in Co‐Doped Mn3Sn Noncoplanar Antiferromagnets

Advanced Science, EarlyView.
Co doping in Mn3Sn transforms the spin texture magnetic state from a coplanar noncollinear magnetic state into a noncoplanar one, resulting in a large topological Hall effect (THE) over a wide temperature range (2–300 K). The THE arises from a noncoplanar spin texture, driven by lattice distortion and enhanced out‐of‐plane Dzyaloshinskii ...
