Campylobacter jejuni 11168H Exposed to Penicillin Forms Persister Cells and Cells With Altered Redox Protein Activity

open access: yesFrontiers in Cellular and Infection Microbiology, 2020
The formation of persister cells is one mechanism by which bacteria can survive exposure to environmental stresses. We show that Campylobacter jejuni 11168H forms persister cells at a frequency of 10−3 after exposure to 100 × MIC of penicillin G for 24 h.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Analysis of transport properties and photoconductive response of single InAs nanowires [PDF]

open access: yes, 2009
Semiconductor nanowires are artificial structures of nanometer size with an approximately cylindric shape. They have an aspect ratio much larger than one so that, in most instances, they can be considered 1D systems.

ELECTRON BEAM TRANSPORT IN DIELECTRIC TUBES

open access: yesEast European Journal of Physics, 2014
The present paper outlines the results of experimental studying the transport process of pulse high-current beam of electrons about 200 ns in duration with energy under 200 keV through straight and bent glass tubes. A 17 degrees deviation of the electron

Role of Second Quinone Binding Site in Proton Pumping by Respiratory Complex I

open access: yesFrontiers in Chemistry, 2019
Respiratory complex I performs the reduction of quinone (Q) to quinol (QH2) and pumps protons across the membrane. Structural data on complex I have provided spectacular insights into the electron and proton transfer paths, as well as into the long (~30 ...

Electronic Transport in Antiaromatic Molecules

open access: yesPhysical Chemistry Chemical Physics
It has been pointed out that antiaromaticity may, under certain conditions, enhance electron transport. Here, we explore this relationship by analyzing a representative series of antiaromatic molecules, ranging from small and large-sized monocyclic systems to polycyclic molecules.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

open access: yesFEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Surface-Enhanced Raman Scattering in Molecular Junctions

open access: yesSensors, 2017
Surface-enhanced Raman scattering (SERS) is a surface-sensitive vibrational spectroscopy that allows Raman spectroscopy on a single molecular scale. Here, we present a review of SERS from molecular junctions, in which a single molecule or molecules are ...

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...
