Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The distinct conformational dependence of chemical shifts caused by R-helices and β-sheets renders NMR chemical shift analysis a powerful tool for the structural determination of proteins. However, the time scale of NMR experiments can make a secondary str ...
Enantiopure, monodisperse alleno-acetylenic cyclooligomers were synthesized. The single-crystal x-ray structures of the cyclic trimer and hexamer were resolved, providing insights into the symmetry of these mols. Electronic CD (ECD), ORD, Raman spectroscop ...
GNA2132 (Genome-derived Neisseria Antigen 2132) is a surface-exposed lipoprotein discovered by reverse vaccinology and expressed by genetically diverse Neisseria meningitidis strains (Pizza et al. 2000). The protein induces bactericidal antibodies against ...
In this paper we analyze the vibrational spectra of a large ensemble of non-homologous protein structures by means of a novel tool, that we coin Hierarchical Network Model (HNM). Our coarse-grained scheme accounts for the intrinsic heterogeneity of force c ...
Protein powder diffraction is shown to be suitable for obtaining de novo solutions to the phase problem at low resolution via phasing methods such as the isomorphous replacement method. Two heavy-atom derivatives (a gadolinium derivative and a holmium deri ...
The respirasome is a multisubunit supercomplex of the respiratory chain in mitochondria. Here we report the 3D reconstruction of the bovine heart respirasome, composed of dimeric complex III and single copies of complex I and IV, at about 2.2-nm resolution ...

Polarization dependent vanadium L edge x-ray absorption spectra of BaVS3 single crystals are measured in the four phases of the compound. The difference between signals with the polarizations E perpendicular to c and E parallel to c ( linear dichroism) cha ...
Lysozyme can be electrochemically detected after adsorption at an electrified gel-water interface. Ex-situ characterization by electrostatic spray ionization mass spectrometry provides insights into the interfacial detection mechanism by allowing changes t ...
Nanoparticles (NPs) in the biological environment are exposed to a large variety and concentration of proteins. Proteins are known to adsorb in a 'corona' like structure on the surface of NPs. In this study, we focus on the effects of surface compositional ...
Interactions of transmembrane (TM) helices play a key role in many cell processes. The configuration and cross angle these helices adopt are traditionally attributed to specific residue interactions. We present a different approach, in which specific resid ...
