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 ...
2023Mechanism 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( ...
2023Ultrafast 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 ...
SWISS CHEMICAL SOC2022Insights into the microbial reduction of pentavalent and hexavalent uranium species by Shewanella oneidensis MR-1
Margaux Camille Andréa Molinas
Decades of uranium-related activities such as ore mining, nuclear power generation, weapon manufacture, storage of nuclear wastes, have contributed to the release of U in the environment. U occurrence is concerning, since in surface environments, U is typi ...
EPFL2021Spin cascade and doming in ferric hemes: Femtosecond X-ray absorption and X-ray emission studies
Majed Chergui, Oliviero Cannelli, Christopher Alexander Arrell, Wojciech Gawelda, Giulia Fulvia Mancini, Frederico Alves Lima, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Rebecca Ann Ingle, Jérémy Raymond Jean Maurice Rouxel, Samuel Menzi
The structure-function relationship is at the heart of biology, and major protein deformations are correlated to specific functions. For ferrous heme proteins, doming is associated with the respiratory function in hemoglobin and myoglobins. Cytochrome c (C ...

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 ...
2020Ultrafast 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 ...
AMER CHEMICAL SOC2019The 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 ...
2018Non-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 ...
2017FOLDING 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 ...
