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.
Alpha-synuclein (α-syn) is a natively unfolded protein that is closely linked to Parkinson’s disease (PD) by genetic, neuropathologic and biochemical evidence. Aggregated and fibrillar forms of α-syn are the main components of intracellular protein inclusi ...
The amino acid sequence determines the individual protein three-dimensional structure and its functioning in an organism. Therefore, "reading" a protein sequence and determining its changes due to mutations or post-translational modifications is one of the ...
Modern methods of cryo electron microscopy and tomography allow visualization of protein nanomachines in their native state at the nanometer scale. Image processing methods including sub-volume averaging applied to repeating macromolecular elements within ...
Imaging of individual protein molecules at the single amino acid level has so far not been possible due to the incompatibility of proteins with the vacuum environment necessary for high-resolution scanning probe microscopy. Here we demonstrate electrospray ...
Proteins have the ability to assemble in multimeric states to perform their specific biological function. Unfortunately, characterizing experimentally these structures at atomistic resolution is usually difficult. For this reason, in silico methodologies a ...
The first tetrameric cation-cation neptunyl(v) cluster, [NpO 2(salen) 4(μ 8-K) 2][K(18C6)Py] 2, has been synthesized in non-aqueous solution from the reaction of [(NpO 2Py 5)(KI 2Py 2)] n with K 2salen and its structure determined in the solid state and in ...
Secretory and membrane proteins attain their native structure in the endoplasmic reticulum (ER). Folding-defective polypeptides are selected for degradation by processes collectively defined as ER-associated degradation (ERAD). Enhanced ERAD activity may i ...
We introduce a new approach to improve structural and dynamical determination of large metalloproteins using solid-state nuclear magnetic resonance (NMR) with H-1 detection under ultrafast magic angle spinning (MAS). The approach is based on the rapid and ...
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 ...
Genome-scale metabolic reconstructions (GSMRs) are valuable resources in the analysis and understanding of cellular metabolism. They are based on genome sequence and annotation, and they are to develop bottom-up mathematical models of metabolic networks. T ...
