Similarities and Differences among Protein Dynamics Studied by Variable Temperature Nuclear Magnetic Resonance Relaxation

David Lyndon Emsley, Jayasubba Reddy Yarava, Andrea Bertarello, Baptiste Busi

Understanding and describing the dynamics of proteins is one of the major challenges in biology. Here, we use multifield variable-temperature NMR longitudinal relaxation (R-1) measurements to determine the hierarchical activation energies of motions of fou ...

Asymmetric opening of the homopentameric 5-HT3A serotonin receptor in lipid bilayers

Horst Arthur Vogel, Shuguang Yuan

Pentameric ligand-gated ion channels (pLGICs) of the Cys-loop receptor family are key players in fast signal transduction throughout the nervous system. They have been shown to be modulated by the lipid environment, however the underlying mechanism is not ...

Insights 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 ...

Passive and active ion permeation through lipid bilayers investigated by second harmonic water imaging

Maksim Eremchev

Lipid membranes are complex and dynamic systems which are known to mediate signaling processes between cells and their environment. To do this multiple ion channels and pumps are involved in controlling the in- and out-flux of various ions (K+, Na+, Mg2+, ...

The Nt17 Domain and its Helical Conformation Regulate the Aggregation, Cellular Properties and Neurotoxicity of Mutant Huntingtin Exon 1

Giovanni Dietler, Hilal Lashuel, Anass Chiki, Francesco Simone Ruggeri, Anne-Laure Mahul Mellier, Urszula Beata Cendrowska, Sophie Vieweg, Nathan Alain Denis Riguet, Sean Michael Deguire

Converging evidence points to the N-terminal domain comprising the first 17 amino acids of the Huntingtin protein (Nt17) as a key regulator of its aggregation, cellular properties and toxicity. In this study, we further investigated the interplay between N ...

Imaging Cu2+ binding to charged phospholipid membranes by high-throughput second harmonic wide-field microscopy

Sylvie Roke, David Roesel, Seonwoo Lee

The interaction of divalent copper ions (Cu2+) with cell membranes is crucial for a variety of physiological processes of cells, such as hormone synthesis and cellular energy production. These interactions would not be possible without membrane hydration. ...

Molecular Bases of the Membrane Association Mechanism Potentiating Antibiotic Resistance by New Delhi Metallo-beta-lactamase 1

Matteo Dal Peraro, Alessio Prunotto

Resistance to last-resort carbapenem antibiotics is an increasing threat to human health, as it critically limits therapeutic options. Metallo-beta-lactamases (MBLs) are the largest family of carbapenemases, enzymes that inactivate these drugs. Among MBLs, ...

Outer membrane lipoprotein NlpI scaffolds peptidoglycan hydrolases within multi-enzyme complexes in Escherichia coli

Ann-Kristin Hov

The peptidoglycan (PG) sacculus provides bacteria with the mechanical strength to maintain cell shape and resist osmotic stress. Enlargement of the mesh-like sacculus requires the combined activity of peptidoglycan synthases and hydrolases. In Escherichia ...
