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( ...

Ultrafast X-ray Spectroscopy of Haem Proteins

Majed Chergui, Camila Bacellar Cases Da Silveira

In this article we revisit our recent picosecond and femtosecond X-ray absorption spectroscopy (XAS) and X-ray emission spectroscopy (XES) experiments, probing the ultrafast electronic and geometric evolution of photoexcited haem proteins, namely ferrous N ...

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 ...

Ultrafast Broadband Fluorescence Up-conversion Study of the Electronic Relaxation of Metalloporphyrins

Majed Chergui, Andrea Cannizzo, Olivier Christian Bräm

We present a systematic study of the ultrafast fluorescence with broadband detection and similar to 110 fs resolution of 5,10,15,20-tetraphenylporphin (TPP) and 2,3,7,8,12,13,17,18-oc-taethylporphin (OEP), with open 3d-shell metals. We also revisit the cas ...

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 ...

Non-invasive continuous monitoring of pro-oxidant effects of engineered nanoparticles on aquatic microorganisms

Olivier Martin, Paul Bowen, Christian Santschi, Volodymyr Koman, Nadia Rachel Von Moos

Engineered nanomaterials (ENMs) are key drivers for the development of highly sophisticated new technologies. As all new attainments, the rapidly increasing used of ENMs raise concerns about their safety for the environment and humans. There is growing evi ...

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 ...
