[NMR paper] Acetonitrile allows indirect replacement of non-deuterated lipid detergents by deuterated lipid detergents for the NMR study of detergent-soluble proteins
Acetonitrile allows indirect replacement of non-deuterated lipid detergents by deuterated lipid detergents for the NMR study of detergent-soluble proteins
Detergent-soluble proteins (DSPs) are commonly dissolved in lipid buffers for NMR experiments, but the huge lipid proton signal prevents recording of high-quality spectra. The use of costly deuterated lipids is thus required to replace non-deuterated ones. With conventional methods, detergents like dodecylphosphocholine (DPC) cannot be fully exchanged due to their high binding affinity to hydrophobic proteins. We propose an original and simple protocol which combines the use of acetonitrile,...

[NMR paper] Dicarboxylate-Oside Detergents for Extraction, Overstabilization and Crystallization of Membrane Proteins
Dicarboxylate-Oside Detergents for Extraction, Overstabilization and Crystallization of Membrane Proteins
To tackle the problem of membrane proteins (MPs) instability in detergent solutions, we designed a series of dicarboxylate-oside detergents (DCODs) in which we optimized the polar head to clamp the membrane domain, including on one side a cluster of two carboxyl groups that promotes salt-bridges with basic residues abundant at the membrane-cytoplasm interface of MPs, and on the other side a sugar to generate H-bonds. Tested on BmrA, an ATP-binding cassette pump, DCODs 8b, 8c, and 9b...
