Surfactants are commonly used in biopharmaceutical formulations to stabilize proteins against aggregation. However, the choice of a suitable surfactant for a particular protein is decided mostly empirically, and their mechanism of action on molecular level is largely unknown. Here we show that a straightforward label-free method, saturation transfer difference (STD) nuclear magnetic resonance (NMR) spectroscopy, can be used to detect protein-surfactant interactions in formulations of a model...
[NMR paper] Membrane Interactions of alpha-Synuclein Revealed by Multiscale Molecular Dynamics Simulations, Markov State Models, and NMR
Membrane Interactions of alpha-Synuclein Revealed by Multiscale Molecular Dynamics Simulations, Markov State Models, and NMR
?-Synuclein (?S) is a presynaptic protein that binds to cell membranes and is linked to Parkinson's disease (PD). Binding of ?S to membranes is a likely first step in the molecular pathophysiology of PD. The ?S molecule can adopt multiple conformations, being largely disordered in water, adopting a ?-sheet conformation when present in amyloid fibrils, and forming a dynamic multiplicity of ?-helical conformations when bound to lipid bilayers and related...

Abstract
Elucidating the structural details of proteins is highly valuable and important for the proper understanding of protein function. In the case of intrinsically disordered proteins (IDPs), however, obtaining the structural details is quite challenging, as the traditional...

Gemini surfactants have two polar head groups and two hydrocarbon tails. Compared with conventional surfactants, geminis have much lower (?M vs. mM) critical micelle concentrations and possess slower (ms vs. ?s) monomer ? micelle kinetics. The structure of the gemini surfactants studied is ·2Br- where s =4, 5, or 6. Our objective is to reveal the effect...
