Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase

Angewandte Chemie, EarlyView.
From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.

Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes

Angewandte Chemie, EarlyView.
The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...

A Hybrid Ultramicroporous Material Family With Metal‐Controlled Dynamic Behavior

Angewandte Chemie, EarlyView.
The hybrid ultramicroporous material (HUM) family NbOFFIVE‐3,3'‐bpy‐M exhibits metal‐dependent dynamic behavior upon exposure to water vapor. Whereas the Co and Ni variants undergo reversible lp→np→lp induced‐fit transformation, Cu and Zn exhibit a more typical np→lp mechanism.

Chemoenzymatic Synthesis of 6‐Sulfo Sialyl Lewisx Containing Glycans to Probe the Receptor Specificity of MERS Coronavirus

Angewandte Chemie, EarlyView.
A chemoenzymatic methodology is described that provided a panel of 6‐sulfo sialyl Lewisx‐containing glycans that were probed for receptor specificity of MERS‐CoV. Although the fucoside of 6‐sulfo‐SLex does not directly interact with the spike, it pre‐organizes the molecule into a conformation to allow a salt bridge between the sulfate and the ...
