Speciation-dependent kinetics of uranium(VI) bioreduction

Rizlan Bernier-Latmani, Harish Veeramani

The kinetics of uranium(VI) reduction by Shewanella oneidensis strain MR-1 was studied for varied pH and concentrations of dissolved inorganic carbon (DIC) and calcium. These are key variables affecting U(VI) speciation in aqueous systems. For all conditio ...

Understanding amyloid aggregation by statistical analysis of atomic force microscopy images

Giovanni Dietler, Paolo De Los Rios, Jérôme Flakowski, Raffaele Mezzenga

The aggregation of proteins is central to many aspects of daily life, including food processing, blood coagulation, eye cataract formation disease and prion-related neurodegenerative infections[1–5]. However, the physical mechanisms responsible for amyloid ...

Kinetic hard-modelling and spectral validation of rank-deficient spectroscopic data

Julien Léo Billeter, Konrad Hungerbühler

In recent years, chemometric methods for the analysis of multivariate kinetic data have considerably progressed. Kinetic hard-modelling is one of these methods that is based on the rate law and used to determine the kinetic parameters (e.g. rate constants) ...

Solute energy based REMD

Molecular dynamics (MD) simulations have increasingly contributed to the understanding of biomolecular processes, allowing for predictions of thermodynamic and structural properties. Unfortunately, the holy grail of protein structure prediction was soon fo ...

Amyloid ß-derived switch-peptides as tool to study conformational changes relevant in degenerative diseases

Marie-Stéphanie Camus

The rapid growing number of patients diagnosed with a neurodegenerative disease and more particularly with Alzheimer's disease (AD) has stimulated intensive research in determining and understanding biological phenomena causing such devastating diseases an ...

The fold of alpha-synuclein fibrils

Henning Paul-Julius Stahlberg

The aggregation of proteins into amyloid fibrils is associated with several neurodegenerative diseases. In Parkinson's disease it is believed that the aggregation of a-synuclein (alpha-syn) from monomers by intermediates into amyloid fibrils is the toxic d ...

New methods for the investigation of RNA refolding by NMR spectroscopy

Philipp Wenter

A detailed characterization of the time scales and mechanisms by which RNA molecules change their folding structure upon binding of metabolites or during catalysis is important for the understanding of the different biological functions of RNA. The folding ...

Switch peptides

Incorrect folding of proteins, leading to aggregation and amyloid formation, is associated with a group of degenerative diseases including Alzheimer's disease and late onset diabetes. Amyloid forming proteins are believed to be mainly α-helical in their na ...

From hexamer to amyloid: marginal stability of apolipoprotein SAA2.2 leads to in vitro fibril formation at physiological temperature

Hilal Lashuel

Serum amyloid A (SAA) is a major acute phase reactant and a small apolipoprotein of high density lipoproteins (HDL) in the serum. In cases of prolonged inflammation, SAA may form amyloid fibrils, leading to the disease of amyloid A (AA) amyloidosis. Recent ...

Amyloid fibril formation by macrophage migration inhibitory factor

Hilal Lashuel

We demonstrate herein that human macrophage migration inhibitory factor (MIF), a pro-inflammatory cytokine expressed in the brain and not previously considered to be amyloidogenic, forms amyloid fibrils similar to those derived from the disease associated ...
