FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Scattering of p-Modes by a thin magnetic flux tube [PDF]
, 2007 There is strong observational evidence for solar p-modes being scattered by sunspots. Understanding and comparing phase shifts or travel time delays of scattered waves can present an opportunity to deduce the subsurface structure of sunspots from the ...

π-fluxes, semimetals, and flat bands in artificial materials
Physical Review Research, 2019 The possibility of engineering experimentally viable systems that realize gauge fluxes within plaquettes of hopping has been the subject of a search for decades due to vast amounts of theoretical study. This is of particular interest for topological band

FEBS Letters, EarlyView.The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Amplitude suppression and absorption of p-modes in magnetic flux tube [PDF]
, 2008 The interaction of p-modes (acoustic waves) with a magnetic flux tube is investigated. A set of linearized MHD equations is solved numerically in a two-dimensional domainwith cylindrical geometry.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells
