Comparison of the functional properties of trimeric and monomeric CaiT of Escherichia coli

Secondary transporters exist as monomers, dimers or higher state oligomers. The significance of the oligomeric state is only partially understood. Here, the significance of the trimeric state of the L-carnitine/gamma-butyrobetaine antiporter CaiT of Escher ...

Detecting topological variations of DNA at single-molecule level

Aleksandra Radenovic, Georg Fantner, Adrian Pascal Nievergelt, Ke Liu

In addition to their use in DNA sequencing, ultrathin nanopore membranes have potential applications in detecting topological variations in deoxyribonucleic acid (DNA). This is due to the fact that when topologically edited DNA molecules, driven by electro ...

Involvement of respiratory complex I in organohalide respiration?

Christof Holliger, Julien Maillard, Mathilde Stéphanie Willemin

Abstract Background The NADH:ubiquinone oxidoreductase (Nuo) is an assembly of proteins also known as complex I. It is the entry point for highly energetic electrons in the classical aerobic respiration process as it couples the transfer of two electrons f ...

Identifying the role of complex I in organohalide respiration of Firmicutes

Christof Holliger, Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin

Organohalide-respiring bacteria (OHRB) are capable to link energy conservation with the use of organohalide compounds as terminal electron acceptors. While obligate OHRB relies only on this process for growing, facultative OHRB are able to use alternative ...

Inkjet Printed Nanohydrogel Coated Carbon Nanotubes Electrodes For Matrix Independent Sensing

Hubert Girault, Andreas Stephan Lesch, Fernando Cortes Salazar, Véronique Amstutz

Polyacrylamide (PA) based hydrogels are used in several applications including polyacrylamide gel electrophoresis and sensing devices. Homogeneous and compact PA films can be prepared based on chemical or photopolymerization processes. However, the accurat ...

Composite hydrogel-loaded alumina membranes for nanofluidic molecular filtration

Jürgen Brugger, Philippe Renaud, Arnaud Bertsch, Fabien Patrick Wildhaber, Songmei Wu, Thomas Michael Braschler, Rebekka Anker

In this paper a nanofluidic molecular filtration system based on soft alginate hydrogel fillings and a solid-state alumina support membrane is presented. The electrostatically controlled diffusion is characterized by partition coefficient of the hydrogel a ...

Influence of the initial state of carbon nanotubes on their colloidal stability under natural conditions

Arnaud Magrez, Laura Sigg

The colloidal stability of dry and suspended carbon nanotubes (CNTs) in the presence of amphiphilic compounds (i.e. natural organic matter or surfactants) at environmentally realistic concentrations was investigated over several days. The suspensions were ...

Dielectrophoresis-based continuous-flow particle microreactor

Raphaël Tornay

This thesis mainly deals with the integration of a microfluidic system for the extraction of micrometric and submicrometric particles from a solution. Traditional methods take from several minutes to hours to separate particles from a solution. Microfluidi ...

pKa Estimation of Ruthenium(II)-Arene PTA Complexes and their Hydrolysis Products via a DFT/Continuum Electrostatics Approach

Paul Joseph Dyson, Ursula Röthlisberger, Christian Gossens, Antoine Dorcier

A combined d. functional theory/continuum electrostatics approach was used to est. the pKa values of metal-based compds. and their hydrolysis products. Specifically, the protonation states and abs. pKa values of [M(h6-arene)(X)(Y)(pta)]n+ (M = Ru or Os; ar ...

Maturation of [NiFe]-hydrogenases in Escherichia coli: the HypC cycle

Melanie Blokesch

Carbamoyl phosphate (CP) has been implicated as an educt for the synthesis of the CO and CN ligands of the metal centre of [NiFe]-hydrogenases in Escherichia coli, since CP synthetase mutants (carAB) are unable to generate active hydrogenases due to a bloc ...
