An Isoprene Lipid-Binding Protein Promotes Eukaryotic Coenzyme Q Biosynthesis

Matteo Dal Peraro, Deniz Aydin

The biosynthesis of coenzyme Q presents a paradigm for how cells surmount hydrophobic barriers in lipid biology. In eukaryotes, CoQ precursors-among nature's most hydrophobic molecules-must somehow be presented to a series of enzymes peripherally associate ...

Chemistry of Lipid Membranes from Models to Living Systems: A Perspective of Hydration, Surface Potential, Curvature, Confinement and Heterogeneity

Sylvie Roke, Orly Bagunu Tarun, Halil Ibrahim Okur

Lipid membranes provide diverse and essential functions in our cells relating to transport, energy harvesting and signaling. This variety of functions is controlled by the molecular architecture, such as the presence of hydrating water, specific chemical c ...

Label-free and charge-sensitive dynamic imaging of lipid membrane hydration on millisecond time scales

Sylvie Roke, Orly Bagunu Tarun

Biological membranes are highly dynamic and complex lipid bilayers, responsible for the fate of living cells. To achieve this function, the hydrating environment is crucial. However, membrane imaging typically neglects water, focusing on the insertion of p ...

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

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

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 ...

Lipid exchange and signaling at ER–Golgi contact sites

Meticulous observations of the cell perinuclear region where the Golgi and the endoplasmic reticulum (ER) networks intermingle have revealed close contact sites of barely 20 nm between these two organelles. Recent studies demonstrate that molecular machine ...

Molecular-level characterization of curved water interfaces with sum frequency and second harmonic scattering

Nikolay Smolentsev

Aqueous interfaces are omnipresent in nature. Some of them are visible: droplets in clouds, aerosols, and surfaces of oceans, lakes, and rivers. Many more surfaces are hidden: water in contact with cell membranes, proteins, and the surface of droplets in e ...

Monitoring Membrane Lipidome Turnover by Metabolic N-15 Labeling and Shotgun Ultra-High-Resolution Orbitrap Fourier Transform Mass Spectrometry

Yury Tsybin, Kristina Srzentic, Konstantin Nagornov

Lipidomes undergo permanent extensive remodeling, but how the turnover rate differs between lipid classes and molecular species is poorly understood. We employed metabolic N-15 labeling and shotgun ultra-high-resolution mass spectrometry (sUHR) to quantify ...
