Stereoselective synthesis of alkenes via base-metal-catalyzed addition reactions to alkynes and activation of hydrogen peroxide and carbon dioxide by iron complexes

Alkene functionality can be found in the majority of natural products, drugs, catalysts and organic materials. Therefore, methods of C-C double bond formation constitute a cornerstone of organic synthesis. Selective formation of either (Z)- or (E)-isomer i ...

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, ...

Grafted semiconductors on PE-films leading to bacterial inactivation: Synthesis, characterization and mechanism

César Pulgarin, Juan Kiwi, Sami Rtimi

This study reports the colloidal preparation FeOx, TiO2 and FeOx-TiO2 grafted on polyethylene (PE) films leading to bacterial inactivation. A fast bacterial inactivation was attained by the FeOx-TiO2 compared to the FeOx-PE film due to the interfacial char ...

Characterization of iron reduction in Clostridium acetobutylicum mutants obtained by targeted and transposon mutagenesis

Matthieu Jonas Valentin Amos

Iron reduction in Gram-positive bacteria is not well understood yet, even if it has been investigated in some extent for Gram-positive bacteria. The mechanisms involved in the delivery of electrons to a solid terminal electron acceptor like iron oxides hav ...

Use of Bacteria To Stabilize Archaeological Iron

Julien Maillard

Iron artifacts are common among the findings of archaeological excavations. The corrosion layer formed on these objects requires stabilization after their recovery, without which the destruction of the item due to physicochemical damage is likely. Current ...

Redox Levels through Constant Fermi-Level ab Initio Molecular Dynamics

Alfredo Pasquarello, Assil Bouzid

We develop a method to determine redox levels of half reactions through the use of ab initio molecular dynamics evolving at constant Fermi energy. This scheme models the effect of an electrode by controlling the charge transfer between the single-particle ...

Properties of Enzymes Involved in Tetrachloroethene Respiration

Géraldine Florence Buttet

Tetrachloroethene (PCE) pollution threatens nature and human health due to its toxic and carcinogenic potential. Due to industrial activities, large amounts of PCE were discharged into the environment over the last decades and represent one of major ground ...

Identification of HcgC as a SAM-Dependent Pyridinol Methyltransferase in [Fe]-Hydrogenase Cofactor Biosynthesis

Xile Hu, Lichen Bai, Tao Xu

Previous retrosynthetic and isotope-labeling studies have indicated that biosynthesis of the iron guanylylpyridinol (FeGP) cofactor of [Fe]-hydrogenase requires a methyltransferase. This hypothetical enzyme covalently attaches the methyl group at the 3-pos ...

FOLDING OF COMPLEX REDOX PROTEINS BY DEDICATED MOLECULAR CHAPERONES

Julien Maillard, Ziad Julier, Corantin Grob

Chlorinated compounds (so-called organohalides) are widespread soil and groundwater pollutants. Only few bacteria have the ability to degrade these compounds via organohalide respiration (OHR). Reductive dehalogenases (RDases) are complex redox enzymes inv ...

Uranium(IV) Terminal Hydrosulfido and Sulfido Complexes: The Nature of the Uranium–Sulfur Bond

Marinella Mazzanti, Julie Renée Michelle Andrez

Herein, we report the synthesis and characterization of a series of terminal uranium(IV) hydrosulfido and sulfido complexes, supported by the hexadentate, tacn-based ligand framework (Ad,MeArO)3tacn3– (= trianion of 1,4,7-tris(3-adamantyl-5-methyl-2-hydrox ...
