The Mononuclear Metal-Binding Site of Mo-Nitrogenase Is Not Required for Activity

The biological N-2-fixation process is catalyzed exclusively by metallocofactor-containing nitrogenases. Structural and spectroscopic studies highlighted the presence of an additional mononuclear metal-binding (MMB) site, which can coordinate Fe in additio ...

Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

Xile Hu, Tao Xu, Lichen Bai

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...

New Techniques for Ancient Proteins: Direct Coupling Analysis Applied on Proteins Involved in Iron Sulfur Cluster Biogenesis

Paolo De Los Rios, Duccio Malinverni

Direct coupling analysis (DCA) is a powerful statistical inference tool used to study protein evolution. It was introduced to predict protein folds and protein-protein interactions, and has also been applied to the prediction of entire interactomes. Here, ...

Electrochemical behaviour of ferrocenes in tributylmethylphosphonium methyl sulfate mixtures with water and 1,2-dichloroethane

Thomas James Stockmann, Zhifeng Ding

Electron transfer (ET) reactions in ionic liquid (IL)vertical bar organic solvent (1,2-dichloroethane, DCE) and IL vertical bar water mixtures were investigated using a Pt disk ultramicroelectrode (UME) along with ferrocene (Fc) and ferrocenemethanol (FcCH ...

Photo-induced dynamics of the heme centers in cytochrome bc(1)

Majed Chergui, Frank van Mourik, Andre Al Haddad, Adrien Alexis Paul Chauvet

The ultrafast response of cytochrome bc1 is investigated for the first time, via transient absorption spectroscopy. The distinct redox potentials of both c(1)- and b-hemes allow for a clear differentiation of their respective signals. We find that while th ...

The cysteine desulfurase IscS of Mycobacterium tuberculosis is involved in iron sulfur cluster biogenesis and oxidative stress defence

Stewart Cole, Florence Pojer, Gaëlle Séraphine Kolly, Jan Lars Rybniker, Jeffrey Chen

The complex multiprotein systems for the assembly of protein-bound iron sulfur (Fe S) clusters are well defined in Gram-negative model organisms. However, little is known about Fe S cluster biogenesis in other bacterial species. The ISC (iron sulfur cluste ...

Crystal Structure and Magnetic Properties of Two New Antiferromagnetic Spin Dimer Compounds; FeTe3O7X (X = Cl, Br)

Jia Liu, Helmuth Berger, Dong Zhang

Two new isostructural layered oxohalides FeTe3O7X (X = Cl, Br) were synthesized by chemical vapor transport reactions, and their crystal structures and magnetic properties were characterized by single-crystal X-ray diffraction, Raman spectroscopy, magnetic ...

Hydrogen Evolution at Liquid–Liquid Interfaces

Hubert Girault, Xile Hu, Heron Vrubel, Bin Su, Raheleh Partovi Nia, Imren Hatay

Blowing bubbles: Hydrogen evolution by proton reduction with [(C5Me5)2Fe] occurs at a soft interface between water and 1,2-dichloroethane (DCE). The reaction proceeds by proton transfer assisted by [(C5Me5)2Fe] across the water–DCE interface with subsequen ...

Metal-organic coordination interactions in Fe-Terephthalic acid networks on Cu(100)

Klaus Kern, Giovanni Costantini

Metal-organic coordination interactions are prime candidates for the formation of self-assembled, nanometer-scale periodic networks with room-temperature structural stability. We present X-ray photoelectron spectroscopy measurements of such networks at the ...

A generalised model for dynamic photocurrent responses at dye-sensitised liquid|liquid interfaces

Hubert Girault, Nicolas Eugster, Zdenek Samec

The heterogeneous photoinduced electron transfer involving dyes adsorbed at the interface between two immiscible electrolyte solutions and redox molecules located in the adjacent phase manifests itself as photocurrent responses under potentiostatic conditi ...
