Evidence for Low-Valent Electronic Configurations in Iron-Sulfur Clusters

Alexandra C. Brown et al.

Summary: This study demonstrates that biological iron-sulfur clusters can have a wider range of electronic configurations, including low-valent Fe1+ centers. CO binding to these clusters induces the generation of low-valent Fe1+ states or mixed-valent Fe1.5+Fe2.5+ pairs, leading to remarkable C-O bond activation.

Evidence of substrate binding and product release via belt-sulfur mobilization of the nitrogenase cofactor

Chi Chung Lee et al.

Summary: This study provides direct evidence that N2 is captured on the M-cluster via electron and sulfur depletion, and the N2-captured state is catalytically active in generating NH3. The study also reveals the conditions for product release and the dynamic changes of belt-sulfurs during catalysis. These findings highlight the crucial role of the mobilization of cofactor belt-sulfurs in the nitrogenase reaction.

Second and Outer Coordination Sphere Effects in Nitrogenase, Hydrogenase, Formate Dehydrogenase, and CO Dehydrogenase

Sven T. Stripp et al.

Summary: Gases like H-2, N-2, CO2, and CO are important feedstock for green energy conversion and as sources of nitrogen and carbon. However, their industrial transformation and production require significant energy input, whereas nature efficiently converts them at ambient conditions using gas-processing metalloenzymes (GPMs). In this review, the importance of the cofactor/protein interface in GPMs is emphasized, and the effects of second and outer coordination sphere on catalytic activity are discussed.

Contrasting behaviour under pressure reveals the reasons for pyramidalization in tris(amido)uranium(III) and tris(arylthiolate) uranium(III) molecules

Amy N. Price et al.

Summary: The article explores whether low-coordinate f-block molecules become more planar or pyramidal under pressure using high-pressure crystallography, with the result being dictated by the dipole moment of the complex and the volume of the planar form.

Structural Characterization of Two CO Molecules Bound to the Nitrogenase Active Site

Trixia M. Buscagan et al.

Summary: CO can bind to the FeMo-cofactor of nitrogenase and is both an inhibitor and substrate, undergoing reduction to hydrocarbons. A crystal structure study revealed two CO ligands coordinated to the FeMo-cofactor, suggesting privileged roles for Fe2 and Fe6 in ligand binding with multiple coordination modes available.

Dinitrogen binding and activation at a molybdenum-iron-sulfur cluster

Alex McSkimming et al.

Summary: The study demonstrates that embedding an [MoFe3S4] cluster in a protective ligand environment allows for N-2 binding at Fe; further substitution induces charge transfer, generating Fe-N multiple-bond character; covalent interactions within the cluster play a critical role in N-2 binding and activation.
