Implementation of a flavin biosynthesis operon improves extracellular electron transfer in bioengineered Escherichia coli

Ardemis Anoush Boghossian, Melania Reggente, Mohammed Mouhib

Bioelectrochemical systems (BES) are promising for energy, sensing, environmental, and synthesis applications. Escherichia coli were previously bioengineered for application in BES by introduction of extracellular electron transfer (EET) pathways. Inspired ...

Mechanism of Reduction of Aqueous U(V)-dpaea and Solid-Phase 2 U(VI)-dpaea Complexes: The Role of Multiheme c‑Type Cytochromes

Marinella Mazzanti, Rizlan Bernier-Latmani, Karin Lederballe Meibom, Margaux Camille Andréa Molinas, Radmila Faizova

The biological reduction of soluble U(VI) complexes to form immobile U(IV) species has been proposed to remediate contaminated sites. It is well established that multiheme c-type cytochromes (MHCs) are key mediators of electron transfer to aqueous phase U( ...

Conditional essentiality of a complex I-like enzyme in strict anaerobes: the case of Desulfitobacterium

Christof Holliger, Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Florence Armand

Respiratory complex I is a well-known player in aerobic respiration; it couples the transfer of two electrons from NADH to ubiquinone alongside with proton pumping. Bacterial complex I is usually composed of fourteen subunits forming three different module ...

New 2-Ethylthio-4-methylaminoquinazoline derivatives inhibiting two subunits of cytochrome bc1 in Mycobacterium tuberculosis

Stewart Cole, Andrej Benjak, Anthony Vocat, Jérémie Piton, Shi-Yan Caroline Foo, Andréanne Lupien

The emergence of multi-drug (MDR-TB) and extensively-drug resistant tuberculosis (XDR-TB) is a major threat to the global management of tuberculosis (TB) worldwide. New chemical entities are of need to treat drug-resistant TB. In this study, the mode of ac ...

The small RNA RyhB is a regulator of cytochrome expression in Shewanella oneidensis

Rizlan Bernier-Latmani, Karin Lederballe Meibom

Shewanella oneidensis produces an extensive electron transfer network that results in metabolic flexibility. A large number of c-type cytochromes are expressed by S. oneidensis and these function as the fundamental electron transport chain proteins. Althou ...

Arylvinylpiperazine Amides, a New Class of Potent Inhibitors Targeting QcrB of Mycobacterium tuberculosis

Stewart Cole, Andrej Benjak, Anthony Vocat, Jérémie Piton, Shi-Yan Caroline Foo, Andréanne Lupien, Raphael Christopher Sommer

New drugs are needed to control the current tuberculosis (TB) pandemic caused by infection with Mycobacterium tuberculosis. We report here on our work with AX-35, an arylvinylpiperazine amide, and four related analogs, which are potent antitubercular agent ...

Photo-induced oxidation of the uniquely liganded heme f in the cytochrome b(6)f complex of oxygenic photosynthesis

Frank van Mourik, Andre Al Haddad, Adrien Alexis Paul Chauvet, Rachna Agarwal

The ultrafast behavior of the ferrous heme f from the cytochrome b(6)f complex of oxygenic photosynthesis is revealed by means of transient absorption spectroscopy. Benefiting from the use of microfluidic technologies for handling the sample as well as fro ...
