BAF restricts cGAS on nuclear DNA to prevent innate immune activation

Mahmut Selman Sakar, Beat Fierz, Andrea Ablasser, Baptiste Claude André Guey, Alexiane Clara Decout, Murat Kaynak, Kristina Makasheva, Marilena Wischnewski

The appearance of DNA in the cytosol is perceived as a danger signal that stimulates potent immune responses through cyclic guanosine monophosphate–adenosine monophosphate synthase (cGAS). How cells regulate the activity of cGAS toward self-DNA and guard a ...

Two-dimensional Material Membranes for Gas Separation

Mostapha Dakhchoune

Two-dimensional (2D) materials with atom- or few-atoms-thick layers have emerged as building-blocks in the synthesis of the next-generation membrane-based separations. Generally, 2D material-based membranes display high permeation and high selectivity due ...

Ultraviolet Photodissociation of Peptides: New Insight on the Mobile Proton Model

Aleksandr Pereverzev, Elizaveta Solovyeva

In this work, we study the mechanism of peptide photodissociation by ultraviolet irradiation at 193 nm wavelength and discuss the role of ionization proton in this process. We found that substituting the ionization proton for the alkali metal cations (sodi ...

Kleptoplastidic benthic foraminifera from aphotic habitats: insights into assimilation of inorganic C, N and S studied with sub-cellular resolution

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

The assimilation of inorganic compounds in foraminiferal metabolism compared to predation or organic matter assimilation is unknown. Here, we investigate possible inorganic-compound assimilation in Nonionellina labradorica, a common kleptoplastidic benthic ...

On the comparison between differential vibrational spectroscopy spectra and theoretical data in the carboxyl region of photosystem II

Daniele Narzi, Leonardo Guidoni

Understanding the structural modification experienced by the Mn4CaO5 oxygen-evolving complex of photosystem II along the Kok-Joliot's cycle has been a challenge for both theory and experiments since many decades. In particular, differential infrared spectr ...

Photoactivation of silicon rhodamines via a light-induced protonation

Kai Johnsson, Luc Reymond, Michelle Susanne Frei

Photoactivatable fluorophores are important for single-particle tracking and super-resolution microscopy. Here we present a photoactivatable fluorophore that forms a bright silicon rhodamine derivative through a light-dependent protonation. In contrast to ...

Structure of a PSI-LHCI-cyt b(6)f supercomplex in Chlamydomonas reinhardtii promoting cyclic electron flow under anaerobic conditions

Henning Paul-Julius Stahlberg

Photosynthetic linear electron flow (LEF) produces ATP and NADPH, while cyclic electron flow (CEF) exclusively drives photophosphorylation to supply extra ATP. The fine-tuning of linear and cyclic electron transport levels allows photosynthetic organisms t ...

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 ...

Inorganic carbon and nitrogen assimilation in cellular compartments of a benthic kleptoplastic foraminifer

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin, Maria-Evangelia Giovani

Haynesina germanica, an ubiquitous benthic foraminifer in intertidal mudflats, has the remarkable ability to isolate, sequester, and use chloroplasts from microalgae. The photosynthetic functionality of these kleptoplasts has been demonstrated by measuring ...

Resolving molecule-specific information in dynamic lipid membrane processes with multi-resonant infrared metasurfaces

Hilal Lashuel, Hatice Altug, Nadine Aït Bouziad, Andreas Tittl, Aurélian Michel John-Herpin, Daniel Rodrigo Lopez, Odeta Limaj, Christopher David Kelly

A multitude of biological processes are enabled by complex interactions between lipid membranes and proteins. To understand such dynamic processes, it is crucial to differentiate the constituent biomolecular species and track their individual time evolutio ...
