Redox Properties of Flavin in BLUF and LOV Photoreceptor Proteins from Hybrid QM/MM Molecular Dynamics Simulation

Flavins play an important role in many oxidation and reduction processes in biological systems. For example, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) are common cofactors found in enzymatic proteins that use the special redox prope ...

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 ...

A locally activatable sensor for robust quantification of organellar glutathione

Pablo Rivera Fuentes, Sarah Emmert, Gianluca Quargnali

Glutathione (GSH) is the main determinant of intracellular redox potential and participates in multiple cellular signalling pathways. Achieving a detailed understanding of intracellular GSH homeostasis depends on the development of tools to map GSH compart ...

The mitochondrial calcium uniporter (MCU) activates mitochondrial respiration and enhances mobility by regulating mitochondrial redox state

Sonia Karaz, Umberto De Marchi, Vincenzo Sorrentino, Federico Sizzano

Regulation of mitochondrial redox balance is emerging as a key event for cell signaling in both physiological and pathological conditions. However, the link between the mitochondrial redox state and the modulation of these conditions remains poorly defined ...

Reoxidation of Reduced Peat Organic Matter by Dissolved Oxygen: Combined Laboratory Column‐Breakthrough Experiments and In‐Field Push‐Pull Tests

Meret Aeppli

Electron transfer to peat particulate organic matter (POM) as terminal electron acceptor (TEA) in anaerobic respiration has been hypothesized to lower methane emissions from peatlands by competitively suppressing methanogenesis and/or allowing for anaerobi ...

Adsorption Behavior of the Coenzyme NADH at the Carbon/ Electrolyte Interface Determined by Neutron Reflectometry

The adsorption behavior of beta-nicotinamide adenine dinucleotide (NADH) at the carbon/electrolyte interface has been studied using a combination of neutron reflectometry (NR) and solution depletion isotherms. Coupling the NR technique with an electrochemi ...

Balancing NAD(+) deficits with nicotinamide riboside: therapeutic possibilities and limitations

Carlos Canto Alvarez

Alterations in cellular nicotinamide adenine dinucleotide (NAD(+)) levels have been observed in multiple lifestyle and age-related medical conditions. This has led to the hypothesis that dietary supplementation with NAD(+) precursors, or vitamin B3s, could ...

Clathrin-associated AP-1 control stermination of STING signalling

Andrea Ablasser, Jonathan Jean-Pierre Ricci, Chong Liu, Pengbiao Xu, Ying Liu, Sophie Marie Elisabeth Rivara

Stimulator of interferon genes (STING) functions downstream of cyclic GMP-AMP synthase in DNA sensing or as a direct receptor for bacterial cyclic dinucleotides and small molecules to activate immunity during infection, cancer and immunotherapy(1-10). Prec ...

Taming the radical cation intermediate enabled one-step access to structurally diverse lignans

Jieping Zhu, Cédric Fung, Qiang Wang, Jia-Chen Xiang

Lignans, in spite of their structural diversity, are all biosynthetically derived from coniferyl alcohol. We report herein a divergent synthesis of lignans from biomass-derived monolignols in a short synthetic sequence. Blue LED irradiation of a dichlorome ...

Raman microspectroscopy reveals unsaturation heterogeneity at the lipid droplet level and validates an in vitro model of bone marrow adipocyte subtypes

Olaia Maria Naveiras Torres-Quiroga, Charles Christopher Bataclan, Vasco Ledebur de Antas de Campos, Josefine Catharina Pedersen Tratwal, Daniel Naveed Tavakol

Bone marrow adipocytes (BMAds) constitute the most abundant stromal component of adult human bone marrow. Two subtypes of BMAds have been described, the more labile regulated adipocytes (rBMAds) and the more stable constitutive adipocytes (cBMAds), which d ...
